Help with choosing a tape drive please.
The plan is for our main site to have a NAS for all Veeam backups and these backups will be replicated to our secondary DR site which will also have a NAS.
Monthly archival backups will still be required though and after looking at the options it seems that tape is by far the least expensive option compared to all the (expensive!) cloud backup options.
Our full backup size will be around 6-7 TB, so a new LTO 7 drive may be enough, but since we have so many LTO 5 tapes in use already (as well as the drives) I was thinking of getting a refurbished Dell 124T as a short term measure.
Since the backup is only once per month it's fine for the backup to take 12-15 hours at the weekend, and fit onto 4-5 tapes (according to my calculations).
Is there anything wrong with my thoughts above or does anyone recommend a different model?
