Your network contains a server named Server1 that runs Windows Server 2012.
Server1 has the Hyper-V server role installed.
Server1 hosts four virtual machines named VM1, VM2,VM3, and VM4.
Server1 is configured as shown in the following table.

Backup Operations in Hyper-V
No VSS Writer Available?
In some cases, you need an application-consistent backup but there is no VSS writer available. One example of
this is MySQL. Hyper-V backups of virtual machines containing MySQL will always result in either a crash-consistent or an image-level backup. For MySQL, thelatter is probably acceptable as MySQL doesnt
perpetually expand the log file. However, if youreusing MySQL within a VSS-aware VM, then a Hyper-V-based
backup tool is going to take a crash-consistent backup. MySQL (like any other database system) isnt always
recoverable from a crash-consistent backup; even when recovery is possible, it may be painful. MySQL is just
one example; any number of line-of-business applications could tell a similar tale. In the case of MySQL, one
solution is to find a guest-level backup application that is MySQL-aware and can back it up properly. For
applications for which no backup application has a plug-in, you may need to have pre- and post-backup scripts
that stop services or close applications. If brief downtime is acceptable, you can disable the Backup item
in Hyper-V Integration Services, thereby forcing Hyper-V to save the state of the VM during backup.
This technique results in an image-level backup andcan be used on any application that doesnt have aVSS
writer.
