Hi all!
I stumbled across an older post from Tom Sightler here: https://forums.veeam.com/post137077.html#p137077
The content still holds true and to summarise:
- If using LTO5 or older (which hopefully no one is doing for new deployments): Disable hardware compression unless your Veeam backups have compression disabled
- For LTO6 and newer: Keep hardware compression enabled but don’t expect big savings, maybe put 2.6-2.7 TB on a 2.5 TB media.
The reason it makes sense to keep it on is the new algorithm recognises already compressed data and passes it through.
