<![CDATA[Changing delta backup schedules breaks backups.]]>I was changing a delta backup schedule to see how much data would be transferred at different delta intervals. I had it set at one hour but changed to 10 minutes, 15 and then back to 1 hour. After this I get failed backups. The error indicates that XO can't find the correct vhd file.

Is this a known issue? If it is then perhaps a warning should be in place and that previous snaps are removed?

It has all available patches. I'm using xcp-ng 7.6 which is also updated.

If the old, there is a known bug that caused an issue similar to this.

The solution was to just use the new backup.
