Using zstd instead of gzip for backups

Don’t you want to use zstd for backups? The resulting size may be similar (gzip), but it takes much less time.

p.s. hestia is nice cp :wink:

+1, this is a good suggestion. I saw proxmox lately switching to zstd as well.
gzip esp. with a high level of compression isn’t so effective and interesting anymore…

Yep, looks impressive. (I’ve started using it in Proxmox.)

I agree very good compression protocol, it was designed by developers at Facebook. I would like this as well added much better option @Hexaris can you please open up a github feature request for this! Any yes I agree Hestia is a nice Control Panel.

A different data set - a small Proxmox VM
gzip

zst

It’d be interesting to compare zst with bz2 though - a well established and commonly installed gzip replacement/alternative.

That’s enough to put me off right away! :-o

Im wondering what the System Load Diff between the two

Think zstd is a clear winner…
