mirror backup to S3
-
Unless im am not truly understanding what your asking.
I have 1 backup job. That job has 2 schedules. One for daily incremental backups and one that has the force full backup checked. The full backup only runs on Sunday. The incremental does not run on Sunday.
When creating the sequence job it uses the schedules from that job to create the sequence job.
-
@acebmxer Not a backup job, a backup sequence.
Jobs are for creating separate backups on (usually different schedules).
Sequences are Backup and then do XYZ.

@acebmxer [excuse for the poor english!]
i've now this situation:
1 backup job with two disables schedules, one full and one delta, to a nas
1 mirror full backup to wasabi (S3)
1 mirror incremental backupi've insert two sequences:
one starting at sunday for full backup (the sequence is full backup and then full mirror)
one every 3 hours with delta backup and then mirror incrementalthe job start at the correct hour but the mirror incremental send every time the same data size..

What i posted was just examples of how i have my backups configured. You dont have to call the backup jobs the same as mine. Maybe someone else with more experience can step in. Double check your schedules make sure you did set incorrect settings in one of the schedules/jobs.
-
@acebmxer of course, this is only a test.
the problem is not the schedulng but why incremental send every time all data. -
@robyt said in mirror backup to S3:
1 backup job with two disables schedules, one full and one delta, to a nas
Hi robyt
i the mirror settings : full mirror if when mirroring full backup ( called backup ) , as one file per VM
The incremental mirror will take care on all the files created by a delta backupCan you show me what retention you have on both side ? you have more explanation on the syncrohnization algorithm here https://docs.xen-orchestra.com/mirror_backup , to be short a delta mirror can only be done if part of the disks chains are common to both remotes
-
@florent hi, i've adjusted the retention parameters and i'm waiting for some days of backup/mirror for checking
-
Hi @florent, i've clean backup data, add the correct retention and now
it's fine
i'm lowering nbd connection (from 4 to 1), the speed of "test backup con mirror" is too low -
@robyt 2 is generally a sweet spot
-
@florent i've a little problem with backup to s3/wasabi..
for delta seems all ok:
