XOA Full Backups consumes to much SR space.
I would like to request of feature (or just point me to dome setting in XOA) for Full backup mode on BackupNG.
At this moment XOA create a snapshot of all VMs designated for backup as soon as possible at the beginning of the backup.
It it good for semi-consistent backups of multiple VMs but for the cost of SR space on thick-provisioned SR like LVM or LVMoHBA.
If I want to make a full backup of entire host I have to keep at least one half of every my thick-provisoned SR free. It is ridiculous.
So I'm using home-brewed scripts which creating a snapshots prior to export and delete them as soon as export finished or failed. This way I keep minimal amount of free space and have full backup, however snapshots timestamp are different.
Would you please add an option to create snapshot right before vm-export and delete them as soon as export finished?
I think this is already possible in XO, using concurrency to 1. I'm not entirely sure, @julien-f ?
edit: also it's time to use a file based SR to get rid of these problems
@olivierlambert Yep, that should be working.
Just found this.
Please, move to "XOA" forum from "Request".
@BogdanRudas so is your issue fixed by using concurrency to 1?
Yes, setting concurrency to 1 helps me. Will try to run concurrency >1 on th pool and see how it works.
When concurrency > 1 it would be nice to split backups per-host (in case of pool) or per-SR (in case of multiple SRs)
