This is not decided yet. We have the proposal to use xorriso with incremental backups on some raw storage devices or on some data files in filesystems on backup disks. We have the proposal to use rsync on backup disks where trees of the original disks get mirrored to backup trees. Typically with the same filesystem type as on the original disks. The main difference between both proposals is in ithe intrinsic backup fidelity of copying between filesystems of the same type (rsync wins) and the capability of incremental backups to retrieve the original state of each update stage of the backup. I.e. you can mount the backup of each day, compare it with other days, or retrieve a file state which has already been replaced by several subsequent backups which recorded the already damaged file. (xorriso wins here.) But the backup fidelity of xorriso is high, and rsync could copy to backup filesystems which are capable of snapshotting their older states. So it is still undecded. ... and some other backup systems have not been mentioned yet. Have a nice day :) Thomas
