doveadm backup only working once?
All,
For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines.
Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc).
My "main" machine is called "server" and the 2nd machine is "server2".
See below for the dovecot -n output on server2.
I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server.
Those testmessages are now present in /var/mail/synctest mbox file on server1.
When trying to create a backup from server->server2 for user synctest I use this command:
#doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw)
The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied
Before I can get a succesfull backup again I need to do this (on server2):
#rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied
Anybody any idea what is happening here? Should I enable replicator and/or aggregator?
Output of 1st and 2nd dovadm backup attempt is below:

This appears to work perfectly well the first time (maybe I am overlooking some issue already at this stage?) At least after the backup has been completed /var/mail/syncuser on server2 contains all the messages that are also present on server1. And the ~syncuser/mail/index/INBOX folder also exists (don't know why this is created btw?)
But then when running the same command for the 2nd time (and no changes on the /var/mail/synctest file on server1) the command failes like this (permission denied to delete INBOX at the end):

All,
Maybe a relevant piece of additional information that could help in figurring out what is going wrong here that I forgot to add in my previous posting.
After the succesfull first backup execution using: #doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345
as described in detail below the /var/mail/synctest inbox file contains this (using mail -f /var/mail/synctest):
root@mail:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 2 messages 2 unread
U 1 torremans@mail.to Mon Jan 04 17:56 29/1016 Testmail 1 U 2 torremans@mail.to Mon Jan 04 17:56 28/982 Testmail 2
After the 2nd backup command (same command) it contains:
root@server2:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 1 message
1 MAILER-DAEMON@ser Wed Jan 06 14:05 13/534 DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Looks like for some reason the inbox file is reset/recreated? Anybody any idea what could cause this behaviour? Running the doveadm backup command a 3rd of 4th time does not change the /var/mail/synctest file anymore. Also the date/time of the file is not updated anymore
Thanks,
Engelbert

All,
For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines.
Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc).
My "main" machine is called "server" and the 2nd machine is "server2".
See below for the dovecot -n output on server2.
I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server.
Those testmessages are now present in /var/mail/synctest mbox file on server1.
When trying to create a backup from server->server2 for user synctest I use this command:
#doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw)
The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied
Before I can get a succesfull backup again I need to do this (on server2):
#rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied
Anybody any idea what is happening here? Should I enable replicator and/or aggregator?
Output of 1st and 2nd dovadm backup attempt is below:

This appears to work perfectly well the first time (maybe I am overlooking some issue already at this stage?) At least after the backup has been completed /var/mail/syncuser on server2 contains all the messages that are also present on server1. And the ~syncuser/mail/index/INBOX folder also exists (don't know why this is created btw?)
But then when running the same command for the 2nd time (and no changes on the /var/mail/synctest file on server1) the command failes like this (permission denied to delete INBOX at the end):

All,
Maybe a relevant piece of additional information that could help in figurring out what is going wrong here that I forgot to add in my previous posting.
After the succesfull first backup execution using: #doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345
as described in detail below the /var/mail/synctest inbox file contains
this (using mail -f /var/mail/synctest):
root@mail:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 2 messages 2 unread
U 1 torremans@mail.to Mon Jan 04 17:56 29/1016 Testmail 1 U 2 torremans@mail.to Mon Jan 04 17:56 28/982 Testmail 2
After the 2nd backup command (same command) it contains:
root@server2:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 1 message
1 MAILER-DAEMON@ser Wed Jan 06 14:05 13/534 DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Looks like for some reason the inbox file is reset/recreated? Anybody any idea what could cause this behaviour? Running the doveadm backup command a 3rd of 4th time does not change the /var/mail/synctest file anymore. Also the date/time of the file is not updated anymore I can't help with your specific problem but you should not use mbox anymore, especially with replication.
Thanks,

All,
For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines.
Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc).
My "main" machine is called "server" and the 2nd machine is
"server2".
See below for the dovecot -n output on server2.
I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server.
Those testmessages are now present in /var/mail/synctest mbox file on
server1.
When trying to create a backup from server->server2 for user synctest
I use this command:
#doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw)
The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied
Before I can get a succesfull backup again I need to do this (on server2):
#rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied
Anybody any idea what is happening here? Should I enable replicator and/or aggregator?
Output of 1st and 2nd dovadm backup attempt is below:

This appears to work perfectly well the first time (maybe I am overlooking some issue already at this stage?) At least after the backup has been completed /var/mail/syncuser on server2 contains all the messages that are also present on server1. And the ~syncuser/mail/index/INBOX folder also exists (don't know why this is
created btw?)
But then when running the same command for the 2nd time (and no changes on the /var/mail/synctest file on server1) the command failes
like this (permission denied to delete INBOX at the end):

Hi!
dsync has limited support to work with mbox format, which is mainly to get away from it.

All,
Maybe a relevant piece of additional information that could help in figurring out what is going wrong here that I forgot to add in my previous posting.
After the succesfull first backup execution using: #doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345
as described in detail below the /var/mail/synctest inbox file contains
this (using mail -f /var/mail/synctest):
root@mail:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 2 messages 2 unread
U 1 torremans@mail.to Mon Jan 04 17:56 29/1016 Testmail 1 U 2 torremans@mail.to Mon Jan 04 17:56 28/982 Testmail 2
After the 2nd backup command (same command) it contains:
root@server2:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 1 message
1 MAILER-DAEMON@ser Wed Jan 06 14:05 13/534 DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Looks like for some reason the inbox file is reset/recreated? Anybody any idea what could cause this behaviour? Running the doveadm backup command a 3rd of 4th time does not change the /var/mail/synctest file anymore. Also the date/time of the file is not updated anymore I can't help with your specific problem but you should not use mbox anymore, especially with replication.
Thanks,

All,
For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines.
Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc).
My "main" machine is called "server" and the 2nd machine is
"server2".
See below for the dovecot -n output on server2.
I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server.
Those testmessages are now present in /var/mail/synctest mbox file on
server1.
When trying to create a backup from server->server2 for user synctest
I use this command:
#doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw)
The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied
Before I can get a succesfull backup again I need to do this (on server2):
#rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied
Anybody any idea what is happening here? Should I enable replicator and/or aggregator?
Output of 1st and 2nd dovadm backup attempt is below:

This appears to work perfectly well the first time (maybe I am overlooking some issue already at this stage?) At least after the backup has been completed /var/mail/syncuser on server2 contains all the messages that are also present on server1. And the ~syncuser/mail/index/INBOX folder also exists (don't know why this is
created btw?)
But then when running the same command for the 2nd time (and no changes on the /var/mail/synctest file on server1) the command failes
like this (permission denied to delete INBOX at the end):

OK. So you are suggesting that moving to mdbox could solve my problem?
I could migrate/reconfigure my "server2" to mdbox while keeping my "production/server1" running on mbox and backup everything from server1->server2 and switch over once everything proves to be working OK.

Hi!
dsync has limited support to work with mbox format, which is mainly to get away from it.

All,
Maybe a relevant piece of additional information that could help in figurring out what is going wrong here that I forgot to add in my previous posting.
After the succesfull first backup execution using: #doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345
as described in detail below the /var/mail/synctest inbox file contains
this (using mail -f /var/mail/synctest):
root@mail:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 2 messages 2 unread
U 1 torremans@mail.to Mon Jan 04 17:56 29/1016 Testmail 1 U 2 torremans@mail.to Mon Jan 04 17:56 28/982 Testmail 2
After the 2nd backup command (same command) it contains:
root@server2:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 1 message
1 MAILER-DAEMON@ser Wed Jan 06 14:05 13/534 DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Looks like for some reason the inbox file is reset/recreated? Anybody any idea what could cause this behaviour? Running the doveadm backup command a 3rd of 4th time does not change the /var/mail/synctest file anymore. Also the date/time of the file is not updated anymore I can't help with your specific problem but you should not use mbox anymore, especially with replication. Thanks,

All,
For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines.
Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc).
My "main" machine is called "server" and the 2nd machine is "server2". See below for the dovecot -n output on server2.
I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server.
Those testmessages are now present in /var/mail/synctest mbox file on server1.
When trying to create a backup from server->server2 for user synctest I use this command:
#doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw)
The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied Before I can get a succesfull backup again I need to do this (on server2): #rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied
Anybody any idea what is happening here? Should I enable replicator and/or aggregator?
Output of 1st and 2nd dovadm backup attempt is below:

This appears to work perfectly well the first time (maybe I am overlooking some issue already at this stage?) At least after the backup has been completed /var/mail/syncuser on server2 contains all the messages that are also present on server1. And the ~syncuser/mail/index/INBOX folder also exists (don't know why this is created btw?)
But then when running the same command for the 2nd time (and no changes on the /var/mail/synctest file on server1) the command failes like this (permission denied to delete INBOX at the end):

I experienced some corruption with mdbox that I had to move away from it to Maildir. Anyway, that's just me,

OK. So you are suggesting that moving to mdbox could solve my problem?
I could migrate/reconfigure my "server2" to mdbox while keeping my "production/server1" running on mbox and backup everything from server1->server2 and switch over once everything proves to be working OK.

Hi!
dsync has limited support to work with mbox format, which is mainly to get away from it.

All,
Maybe a relevant piece of additional information that could help in figurring out what is going wrong here that I forgot to add in my previous posting.
After the succesfull first backup execution using: #doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345
as described in detail below the /var/mail/synctest inbox file contains
this (using mail -f /var/mail/synctest):
root@mail:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 2 messages 2 unread

After the 2nd backup command (same command) it contains:
root@server2:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 1 message
1 MAILER-DAEMON@ser Wed Jan 06 14:05 13/534 DON'T DELETETHIS MESSAGE -- FOLDER INTERNAL DATA
Looks like for some reason the inbox file is reset/recreated? Anybody any idea what could cause this behaviour? Running the doveadm backup command a 3rd of 4th time does not change the /var/mail/synctest file anymore. Also the date/time of the file is not updated anymore I can't help with your specific problem but you should not use mbox anymore, especially with replication. Thanks,

All,
For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines.
Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc).
My "main" machine is called "server" and the 2nd machine is "server2". See below for the dovecot -n output on server2.
I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server.
Those testmessages are now present in /var/mail/synctest mbox file on server1.
When trying to create a backup from server->server2 for user synctest I use this command:
#doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw)
The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied Before I can get a succesfull backup again I need to do this (on server2): #rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied
Anybody any idea what is happening here? Should I enable replicator and/or aggregator?
Output of 1st and 2nd dovadm backup attempt is below:

This appears to work perfectly well the first time (maybe I am overlooking some issue already at this stage?) At least after the backup has been completed /var/mail/syncuser on server2 contains all the messages that are also present on server1. And the ~syncuser/mail/index/INBOX folder also exists (don't know why this is created btw?)
But then when running the same command for the 2nd time (and no changes on the /var/mail/synctest file on server1) the command failes like this (permission denied to delete INBOX at the end):

No, I'm suggesting you use any other mail format than mbox, like maildir, sdbox or mdbox. sdbox or maildir is pretty safe bet.

OK. So you are suggesting that moving to mdbox could solve my problem?
I could migrate/reconfigure my "server2" to mdbox while keeping my "production/server1" running on mbox and backup everything from server1->server2 and switch over once everything proves to be working OK.

Hi!
dsync has limited support to work with mbox format, which is mainly to get away from it.

All,

After the succesfull first backup execution using: #doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345
as described in detail below the /var/mail/synctest inbox file contains
this (using mail -f /var/mail/synctest):
root@mail:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 2 messages 2 unread

After the 2nd backup command (same command) it contains:
root@server2:/var/mail# mail -f synctest Mail version 8.1.2 01/15/2001. Type ? for help. "synctest": 1 message
1 MAILER-DAEMON@ser Wed Jan 06 14:05 13/534 DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Looks like for some reason the inbox file is reset/recreated? Anybody any idea what could cause this behaviour? Running the doveadm backup command a 3rd of 4th time does not change the /var/mail/synctest file anymore. Also the date/time of the file is not updated anymore I can't help with your specific problem but you should not use mbox anymore, especially with replication. Thanks,

All,
For the past 2 weeks I have been trying to get dovecot mail backup working between 2 debian 10 machines.
Both machines are running the same OS (Debian 10) and configuration wise they are similar (except of course ip addresses, hostnames etc).
My "main" machine is called "server" and the 2nd machine is "server2". See below for the dovecot -n output on server2.
I created a testuser called synctest on both server1 and server2 and have sent a couple (2) email messages to synctest@server.
Those testmessages are now present in /var/mail/synctest mbox file on server1.
When trying to create a backup from server->server2 for user synctest I use this command:
#doveadm -D -v backup -R -f -u synctest tcp:192.168.3.1:12345 (using something similar from server1 -> server2 like this: #doveadm -D -v backup -f -u synctest tcp:192.168.3.2:12345 has the same results btw)
The first attempte appears to be working OK but the the 2nd attempt (nothing was changed on server1 before the 2nd attempt) fails with soemthing like: Error: Couldn't delete mailbox INBOX: Permission denied Before I can get a succesfull backup again I need to do this (on server2): #rm /var/mail/synctest #rm -r ~syncuser/mail/index/INBOX #doveadm mailbox delete -u synctest INBOX (if I don't do the rm /var/mail/synctest before the doveadm mailbox delete command I will also get a: Error: Can't delete mailbox INBOX: Permission denied
Anybody any idea what is happening here? Should I enable replicator and/or aggregator?
Output of 1st and 2nd dovadm backup attempt is below:

This appears to work perfectly well the first time (maybe I am overlooking some issue already at this stage?) At least after the backup has been completed /var/mail/syncuser on server2 contains all the messages that are also present on server1. And the ~syncuser/mail/index/INBOX folder also exists (don't know why this is created btw?)
But then when running the same command for the 2nd time (and no changes on the /var/mail/synctest file on server1) the command failes like this (permission denied to delete INBOX at the end):
