Hi Denis,

I'm currently using dar to make backups following an incremental backup
strategy, using  dar_manager to track the incremental backups.

I note that dar has several features for creating a modified copy of an
archive, e.g. using the --merge option to filter an archive, or dar_xform
to resize slices of an existing archive.

I'm wondering if using these features is compatible with an incremental
backup strategy? E.g. if I have a series of 4 backups made incrementally,
and use dar_xform or dar --merge to create a modified copy of one or more
of backups 1 - 3, can I remove the original backup and use the modified
copy in its place? Or would this break the history of changes required for
dar and dar_manager to link a sequence of incremental backups together?

Best,

Scott
