Axigen Migration / DRBD Highly Available Single-Tier Solution

21

Hi Ioan and Marcel,

Maybe it may help base on my existing scenario. I am using rsync on the directory with -avh --delete. My total storage approx 1.2TB and in transfer only around 500-600 gb.

Total Size 1.2TB Speedup 500-600GB

@indreias

A question how we can explicitly say to axigen to store all new incoming on the specific storage (messagesXX) rather than random to all containers. In which result to a larger differences when running incremental backup.

Regards,
Jay

@indreias Will try that this week. But I’m afraid --checksum won’t make a big difference because it would mean transferring the file through the wan to calculate the checksum, which is somehow the same. But I don’t know if it would make any difference if I start a remote ssh server with the rsync command.

@Jay Well, yes, it is not “full full”, but 600 GB (around the same db size here) is still huge. It would be great if I could make an hourly backup. That said, @indreias, it would be great if not all files (or mostly) are touched.

I Will report later.

Quick update on this. I haven’t had the time to test this. But I found that Borg Backup https://www.borgbackup.org/ is doing a blazing fast (encrypted and compressed, rotated) job backing up the Axigen data store. Still have to test the restore, though.

For anyone new to this topic: You still have to use the described snapshot method.
