I'll add one more link that better explains how it works: https://fedoraproject.org/wiki/Features/Virt_Live_Snapshots Pros: This is nice because the snapshot can be done on the live machine and the writes will be sent to the external file. Once the backup of the original VM image file is performed the snapshot can be (and should be) merged back into the original VM image file. Cons: Don't know if this feature is stable enough and I wouldn't put it into production without heavy testing. I am particularly concerned about the merging the snapshot back to the original image's blocks. If it fails in the process of merging blocks that could result in data loss or at least in the longer downtime while the backed up image is restored. -- Josip Deanovic ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
