I've been running continous dsync backups of our Maildirs for a few weeks now, with the destination dsync server using mdbox and SIS. The idea was that the destination server would act as a warm copy of all our active users data.
How many users there are in this installation?
The active servers are using Maildir, and has:
$ df -h /usr/local/atmail/users/ Filesystem Size Used Avail Use% Mounted on /dev/atmailusers 14T 12T 2.2T 85% /usr/local/atmail/users $ df -hi /usr/local/atmail/users/ Filesystem Inodes IUsed IFree IUse% Mounted on /dev/atmailusers 145M 113M 33M 78% /usr/local/atmail/users
very little of this is compressed (zlib plugin enabled during christmas).
This is the old storage in Maildir format?
I'm surprised that the destination server is so large, was expecting zlib and mdbox and SIS would compress it down to much less than what we're seeing (12TB -> 5TB):
$ df -h /srv/mailbackup Filesystem Size Used Avail Use% Mounted on /dev/mapper/mailbackupvg-mailbackuplv 5.7T 4.8T 882G 85% /srv/mailbackup
This is the new storage in mdbox format?
What size you would expect?
