For off-site long-term offline archiving, no, I am not using RAID.

No, it's not LVM+md, just plain LVM for flexibility.

Typically I use 16 TB hard drives, and I tend to use one LV per data
source, the LV name being the data source and the date of the copy.
Or sometimes I just copy a raw volume (ext4 or something else)
to a LV.

With smaller drives (4 TB) I tend to not use LVM, just plain ext4 on the
raw disk.

I almost never use partitionning.

However, I tend to use luks encryption (per ext4 filesystem) when the
drives are stored off-site.  So it's either LVM -> LV -> LUKS -> ext4
or raw disk -> LUKS -> ext4.

You can find some of the scripts I use to automate this off-site
long-term archiving here:
