from what i have read so far, sync driver might lead to some problems and the recommendation is to use VSS driver instead, espacially on exchange or database (sql) servers.

i have also played around with vcb and pre/post backup scripts. when not using VSS (pre/post backup scripts are not executed when using VSS) commands to manually stop applications can be performed before the snapshot is taken. this might work around the problems introduced with sync driver?

so here are my questions:

are there any disadvantages in using VSS over sync driver?

if not, why not always using VSS? if VSS is good enough for database servers, it will be good enough for all other server too?

is there any situation where the sync driver is recommended?

ok i know, VSS is only available on windows, so sync driver migth be the way to go on linux or other non windows systems. what to do on linux based database servers?

how are you guys out there doing your backups?

ps. evaluating veeam backup right now, and like what i have seen so far. but as all the backup solutions i have seen are using VCB, my questions are valid for any other backupsolution too.
