I have various VMs and from those servers I only backup the data and so it will remain for all the reasons you explained to me.
:)
of a single VM, which is a windows10, there is software installed that acts as a switchboard and has various installations to make it work including java and various plug-ins which are not backed up so in case of machine crash to install new the whole switchboard is crazy ...
Agreed. :)
... if I copied the whole VM in case of crash I recover everything including the operating system
Do you experience a lot of crashes? Backups are not meant to be an alternative to running a reliable system. If that is what you are trying to do then perhaps you could configure BackupPC to make only one copy of its backup - so that the deduplication issue is moot - but you would still have to deal with the fact that the operating system will be changing data on the VM faster than BackupPC can copy it so I can't say that I'd recommend this approach. It still feels to me like you ought to be investigating snapshots of some kind. The VM software can probably do that. You could back up user data using BackupPC in the way BackupPC is intended to be used. Now if the VM does crash you could revert to a previously running VM snapshot and just recover the changed user data. It's a two-staged recovery approach, but it would probably be much faster (and yield a more up-to-date result) than taking and recovering full VM copies. https://endoflife.date/windows Which version of Windows 10? -- 73, Ged. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
