Is live snapshot enough for this? Is lvm or san snapshot > recommended? live snapshot gives you crash consistent points in time to return to, howev= er, if you want a 'backup' which is stored externally and can then be resto= red in a different configuration etc then you'd need to utilize the backup = API (live snapshot + attach the snap to a virtual appliance and then back i= t up). live snapshots also integrate with the qemu guest agent so if you've deploy= ed this then you can get better consistency (file systems would be quiesced= on linux guests and on windows guests this should cause VSS to quiesce you= r apps as well). If your storage supports snapshots and your VMs contain a single disk (dire= ct lun) then you can snapshot the lun on the storage side and again get cra= sh consistency. If you could get this to work for you then performance wise this is probabl= y the best option. If your backup solution is integrated with your storage then even better. > * saving the postgres database (or only some of main tables).
