diff from compressed files

Hi,

Currently the cpanel backups on my server creates an uncompressed backup
directory per account with all files from the account. Takes a lot of space.

There is an option to COMPRESS to a tar.gz file for each account. Which
CONSIDERABLY reduce the space.

Is there any way for rsnapshot to sync only the changes _within_
compressed files?

Thanks

For files that rsync copies across a network I believe that its default
behaviour is to only transfer the chunks of the file that have changed,
so if you use that option to create your compressed files it should Just
Work. rsnapshot will still, however, *store* complete copies of every
version of the file.

The new cpanel backup creates an uncompressed tar file for every account.
The legacy cpanel backup used to create an open directory of all the
files associated with an account, making the rsync in rsnapshot work as
expected.

Is there a way to use the NEW cpanel uncompressed tar, and retreive only
the diff?

Thanks
