What are your reasonable options for backing up a 16TB NAS in 2021?
Interface Portability: You do not need any new software or hardware.
Ability to reuse older hardware: Assuming you have a used drive large enough to hold all your backups.
Interface instability: USB3 drives especially are bad at this. The adapters are usually not designed to handle the multiple hours of uptime necessary to complete backing up multiple terabytes of data.
Transfer speeds: Most USB3 drives are not designed for performance. Even custom enclosures with reasonable drives in them usually struggle to keep a sustained write speed of 100MB/s.
