NAS backup
Your NAS still needs a backup.
A NAS protects you from a failed drive. It does not protect you from theft, ransomware, fire, accidental deletion, or losing the entire NAS.
3-2-1
Three copies. Two kinds of media. One offsite.
The shortest useful description of a backup strategy — and the reason a single NAS isn't one.
3
copies
Your working data plus two independent backups.
2
different media
So one failure mode cannot take out every copy.
1
offsite copy
The copy that survives theft, fire and flood.
RAID is not backup
Redundancy keeps a machine running. It does not keep your data.
| Scenario | RAID | Offsite backup |
|---|---|---|
| Disk failure | RAID helps | Protected |
| NAS stolen | RAID does not help | Protected |
| Fire or flood | RAID does not help | Protected |
| Ransomware | RAID may not help | Protected |
| Accidental deletion | RAID does not help | Protected |
