In Unix/Linux is there any max files size limit that a compression utility ( gzip/compress) can compress. I remember years ago it was mentioned in the gzip page that it can compress files up to 4 gb. Actually I need to compress fillies of around 512 GB regularly. I tested few files with compress utility and found hash code(MD5) of the DB files before compress and after un-compress are same.
gzip nowadays can compress files larger than 4 GiB in size, and in fact doesn’t have any limit of its own really (you’ll be limited by the underlying file system). The only limitation with files larger than 4 GiB is that
gzip -l won’t report their size correctly; see Fastest way of working out uncompressed size of large GZIPPED file for an alternative.
Gzip is concatenatable stream comptression (see "advanced usage" in the man page) so if the algorithm hits a hard encoding limit (*) it can just end the current stream and start a new stream.
So there is no hard limit on data size in the gzip itself
(* I don't know enough about
Xflate to say if there is a limit or not)
