I’ve spent the past while buying and experimenting with some old LTO gear as a secondary backup solution besides backing up to both local disks and cloud. I chose LTO because:
- My upload speed is trash so the only way I can hope to do a full off-site backup is via physical media
- With LTO4, it works out cheaper than buying about 2-3x 2+TB external hard disks, especially if you go SCSI instead of SAS.
- I have the option of taking tapes out of rotation and storing them long-term. With hard disks this is risky and expensive.
- Good for air hand luggage
- It’s old school cool
My learnings and notes follow…
