@florent increasing the timeout value was the solution. Thank you.

RE: Missing vdi which is a base for a delta
FWIW it seems to be the same VMs and same VDIs each day. I'm doing some additional experimentation and testing.

Difference between types of metadata backup
Pardon me if this has been asked elsewhere but.. The documentation states:
In Xen Orchestra, Metadata backup is divided into two different options:
Pool metadata backup XO configuration backupWhat is the difference between these?

RE: Missing vdi which is a base for a delta
While you experiment, do the failing VMs have something in common? The same source SR, for example, or a mirror target keeping a different retention than the source.
There are two backup jobs that are failing. One from Ark (local) to Synology, and one from Ark to S3. It seems to be the same VMs failing each night, but interestingly, there are some that fail to Synology but succeed to S3 and vice-versa. There are 9 VMs that fail for both. They do not all share the same SR. The backups on Ark are coming from several delta jobs that run daily, weekly, and monthly. Retention are different for all those.

RE: Missing vdi which is a base for a delta
@acebmxer Of course, sorry. We have XO from sources, currently commit 0be90. I'm not aware of any beta updates? I'm attaching the latest log for one of the jobs.

@poddingue Yes, thanks, I reviewed that post.

RE: Missing vdi which is a base for a delta
I've just removed ALL the backups for one VM and created a new Full backup; When I run the mirror job it again says Missing vdi f04fb96a-5923-4c75-bb42-6c916497885c which is a base for a delta.

Missing vdi which is a base for a delta
Our mirror backup jobs continue to fail about 50% of the VMs with this Missing vdi which is a base for a delta error. I have deleted the data from the remote(s) and the problem comes right back. I'm not sure what is causing it. The backups on the source remote pass health checks.

RE: "Guest tools status"
@kruess That doesn't make sense. It should say the tools are NOT installed.
-
"Guest tools status"
When importing a machine from VMware, Xen Orchestra says "Guest Tools status: The tools are installed." It says this for VMs where VMware tools are not installed.. and furthermore why does it matter when they need to be removed anyway? I'm not understanding what this message is for.
-
Health check scripts. Where is the example?
The documentation for the backup health check states:
An example in bash is shown in @xen-orchestra/backups/docs/healthcheck example/wait30seconds.sh
I'm not clear on where this is actually located nor have I been able to find it. -
