TL;DR (at least not the entire thread)
If you go with Rsync you may find incron an useful add-on as well as with
it you can monitor a variety of events on any given file or directory, like
OPEN_READ, CREATE, CLOSE, CLOSE_WRITE, etc - and this way backup your data
in real time whenever a condition

I second that, this is a very important advice!
In addition, use a good lightning protect
Anyone using RAID of any type: hardware, md, LVM, Btrfs, ZFS, really
need to be aware of drive SCT ERC and kernel SCSI command timer
mismatches. The mismatch happens by default if you're using consumer
hard drives, many of which now either have SCT ERC disabled by default
or do not support it. This

I'd say all data needs at least one backup. Critical stuff should also
be off-site in addition to the local backups. If you won't or can't do

One assumes that if you are migrating a filesystem to RAID, you are installing
a new disk (for e.g. RAID 1) (you need multiple disks - as in the acoronym
RAID).
So, if you install your new disk alongside your existing disk, create a RAID
mirror with only one partition (from the new disk) create
