Backup Continuous Replication hängt!
-
@x-rayd Have you checked source SR to see if it is running low on disk space?
-
I have not done anything!
Today delta backup work perfectly, any ideas? -
Coalesce after snapshot removal (or VDI removal you did), some space we reclaimed automatically.
It was a lack of space on destination SR, your DF Equallogic, probably using thick provisioned.
-
my Equallogic have 12TB space and only 4.5 TB space is used from continuous replication backup!
-
So? As a thick pro SR, every first snapshot will double space needed on the disk size (not space used, total disk size). If you have 4x 2TiB VM disks, a single snapshot of those won't fit.
-
you mean DF Equallogic have not much space?
-
I mean double check source and destination SRs free space.
-
how much % space must be free source and SR?

@x-rayd
If you have 3 VMs that each have a 5TiB disk and you want to back up all of them you need at least 3x5=15TiB on the SR for the initial snapshots. Then you also need some extra GiBs or TiBs for the deltas.The workaround is to set up the SR as EXT, instead of LVM.
Then it's using thin provisioning, meaning that the snapshot only uses as much space as you have data in each 5TiB disk.
So if your VMs are only using 1,3 and 4 TiB of actual disk space then you only need an SR that's 1+3+4=8 TiB + the extra space for the deltas. -
Hello,
for a week cant backup with error: SR_BACKEND_FAILURE_109(, The snapshot chain is too long, )
Why? -
my xo-server 5.57.3
xo-web 5.57.1 -
Please read https://xen-orchestra.com/docs/backup_troubleshooting.html#vdi-chain-protection
If you get to this point, it means you are doing snapshots outside Xen Orchestra

Thanks!

Next problem!
After each backup locale storage have empty disks. Why?
If delete this disks, comming after backup renewed. -
I don't understand what you mean by "empty disk".
-
-
That doesn't help me at all. Also remember I'm not using XCP-ng Center myself. So I really don't get it. Please be really clear, because this way people will be more kindly to help, than trying to understand what you mean exactly.
-
Sorry, I try! But my English is not good!
See now screenshot from XEN Orchestra.
VM DF-Intranet have two snapshots, but one is empty, why? -
That looks like an "orphaned" disk, which should be fine to delete. You can view any existing instances of these by selecting "Orphaned disks" from the filter in the bottom right.
If you experience these on every backup, then there's something off in your setup.

You mean my backup setup?
