Hi!

I used to have three raid1:

2 x 4Tb Ssd dedicated to store personal data

2 x 6Tb HDD dedicated to store "iso's", the eye patched ones.

2 x 4Tb ssd for backup.

Ext4 everywhere.

I run this setup for years, maybe even 20 years (with many different disks and sizes over time).

I decided that was time to be more efficient.

I removed the two HDD, saving quite a lot of power, and switched the four sdd to RAID5, Then put BTRFS on top of that. Please note, I am not using btrfs raid feature, but Linux mdadm software raid (which I have been using rock solid for years) with btrfs on top as if on a single drive.

I choose MD not only for my past very positive experience, but specially because I love how easy is to recover and restore from many issues.

I choose not to try zfs because I don't feel comfortable in using out of kernel drivers and I dislike how zfs seems to be RAM hungry.

What do you guys think?

I saw something about Restic as an alternative to Borgbackup when I was looking around at what to so about backup https://github.com/restic/restic/
