Most, if not all of the visualization hypervisors support virtual machine snapshot. This functionality do not require a special storage with snapshots. I know for sure about VMware and KVM. > If it all > worked, you can delete the snapshot. Or leave it be until the next time. > Well, I think I start to understand what you and Ana wants to say. Yes, you are right Dimitri. In this case she needs snapshots, not a backup tool. Backup tool is required for unplanned downtime and data loss. Any planned downtime should be carefully prepared, especially for planned software upgrades in virtual machines. Snapshots are the best tools for that. > Bacula isn't really the right tool for this. > Exactly. It is a better, faster, easier, just name it, to revert a vm snapshot after upgrade then to restore all required virtual machine disk images data. best regards -- Radosław Korzeniewski rados...@korzeniewski.net
