Are the snapshots taken within elasticsearch repositories compressed in some fairly efficient way by default?
When you "permanently" secure (e.g. BD-ROM) a snapshot repository, is it worth compressing it to some archive (rar, zip, 7z, etc.)?
Does such compression make absolutely no sense and won't give any real size reduction?
My guess is that it might be...
The extra compression is also a very large computational cost.
Is it worth it here to limit myself to a simple tar (tarball) with file splits of specific sizes?
Thanks for your help!
