Hyper-V backups fail with error 2155248001 RRS feed

  • Question

  • I have several Hyper-V boxes where windows server backups are failing. Error message number from event viewer is 2155348001. If I shutdown or save the guests, the backup works. Host os is server 2008r2 with sp1 installed. Guests are server 2003 or winxp. So far I have tried deleting all shadow copy snapshots from the host as well as making sure the guests have enough free space. I have deleted and re-created the backup several times and tried several backup devices ranging from USB to iSCSI to adding a second internal drive array. Guests are also running the newest version of the guest additions. I have one server where I was able to figure out which guest the backup does not like. If I pause or shutdown that one guest, the backup works with the other guest still running. At think the problem is somewhere in Hyper-V, but I am not sure where to look next.
