I prefer DAR for several reasons. First of all, as I mentioned
before, DAR is the only backup solution of which I am aware that can
restore not only deleted or corrupted files, but which can also
restore deletions. This means DAR can restore any or all files one
chooses in a batch, but then if requested can go back and delete
files which were deleted at a later time but prior to additional
DAR backups.
I find it hard to believe that it's a rare feature.
The system I use (`bup`) does support that as well (every backup is
(more or less) a Git commit, so it doesn't distinguish full-backups from
incrementals), but it doesn't bother to mention it probably because it's
very basic.
