So I’ve got a Hyper-V Server with two VMs running, a Domaincontroller and an Exchange Server. I made seperate backup jobs for both and the DC one is running perfectly fine, no errors or warnings. The Exchange job also runs successful but finishes with 4 warnings (3 times failed to process path and one failed to process metadata). Also on the backup jobs Duplicati shows the amount of backup data stored but shows 0 Versions available for restore. Is there something I need to do which I am not aware of when backing up Exchange servers? Note: Had no chance to try copying the files and backing them up without them being “used” by the VM yet.
I think both backups should be using snapshot-policy=required, but I “think” warn you if that’s not so.
Because this uses VSS, Duplicati must be at least an elevated administrator, e.g. SYSTEM service.
You should get a better look at the warnings by watching with About → Show log → Live → Warning
(clicking on lines to expand them). Or you can set up a log-file=<path> to catch warnings and errors.
How many versions does Restore think there are? Did you get a job log? If so, look in Complete log
“BackupListCount” is the version count. You can also view <job> → Show log → Remote’s top lines.
would be a typical reverse-chronological ending with a dlist file listing the files in backup. Got one?
You could also look on the destination using a reverse-chronological sort or a name search for dlist.
If no dlist, then no backup. You could see About → Show log → Stored to look for any other failures.
Backups that don’t complete tend not to leave the usual results log, but may complain to server log.
Duplicati hyper-v has thoughts from another person, but I’m not sure there are any experts available.
Depending on how business-critical these systems are, Duplicati (still in Beta…) might be a poor fit.
