Like most of you, I have a few daily tag.gz snapshot of a folder (of any application). There is only a few different each other but the tar.gz is not a diff/delta friendly format.
Most data in the file should be redundant. Is there a smarter way to repack/re-compress these tar.gz files (e.g. 7 days into one) into a smaller file that could save up to 6/7 disk capacity?
PS. I don't want to change the snapshot part, which is better simple stupid.
PS2. I don't want to delete or cycle either. I have capacity, but dislike redundant.
