Yes all back on track. Just took some time for all the snapshots to be deleted (merged?).

Once complete I was able to run backups again as per normal.

Edit: I just had to wait until all the snapshots were merged and then the next backup worked fine.

Thanks Oliver for the response and advice.

I have removed the rolling snapshot task and will just keep the daily backup process.

How do I fix the error though, as I still get this issue even after I removed all the snapshots and that backup task.

This error is stopping the Delta backup task from running.

Hi All

I have a fairly small setup. 1 XCP-NG host in a single pool with XO running on a VM hosted on a sybology box.

My W2k16 Server VM has rolling snapshots setup through XO to run every 2 hours 7 days a week between 8.30am and 6.30pm. The rentention policy is to keep 30 snap shots.

This VM also has a daily Delta Backup run at 9pm.

Only 2 other VM's on the host that run normal daily delta backups.

Nothing else other than these but I am now getting an error on the Rolling Snapshot task of "SR_BACKEND_FAILURE_109(, The snapshot chain is too long, )"

Is there a recommended limit on the number of snapshots a VM should have? I actually do not how to resolve this issue.

TIA
PD
