Until recently I was able to backup almost everything on a single external 20TB drive; it's no longer the case. What would be the best solution for an ever increasing storage size.

Buy a 22TB or 24TB external drive
- (+) easy
- (-) short term solution
- (-) need to buy another drive
- (-) not growable
Concatenate 2 or 3 drives in a linear RAID (ex: 14TB + 12TB + 8TB = 34TB)
- (+) no need to buy other drives (already have them)
- (+) linear RAID is supported with mdadm on Linux
- (-) no redundancy; like RAID 0, if one drive fails, everything is lost
- (-) not growable
- (-) need a PC or NAS enclosure for the backup
Create a RAID5 with 3 or 4 drives
- (+) redundancy
- (+) growable
- (-) need to buy at least 2 other drives
- (-) need a PC or NAS enclosure for the backup
Deleting files :)
Other options?
