A couple of notes on this quite useful script:
My mktemp does not support -p (FreeBSD 12.1) is I had to change the script to:
In my scripts I tend to create a tempdir and then tempfiles within that. It makes the cleanup routine neater, e.g. at the top of my scripts :
TEMP_DIR=$(mktemp -qd || { doLog "Failed to make temp dir !"; exit 1; }) rmTmpFiles() { rm -rf "${TEMP_DIR}"; } createTempFile() { local MYTEMP=$(mktemp -qp "${TEMP_DIR}" || doLog "Failed to create temp file"; exit 1); echo $MYTEMP; }
I don’t think I need to clean up, and my “temp_dir” will end up being permanent, as to make doveadm backup snappier I will simply maintain the directory there and use crown jobs to update the dir.
Also my backup scripts have locking procedures built-in so as to avoid race conditions.
Also not sure if that’s needed when using doveadm backup, as it takes care of the potential race conditions.
So the idea is to use doveadm to a local folder, then rsync it to a remote server where snapshots can be easily created.
It annoys me have to do the doveadm to the local server - seems like a waste of disk space, but since maildirlock is not working and since doveadm backup to a remote server requires a bit more work to, well, to work, so I guess this is a simple and quick solution.
Best,
