I started using restic over SFTP over local network, my home server to my desktop PC which has external disk attached for backups.
I don’t have exact numbers, but restic over SFTP for me felt significantly slower than “rsync -e ssh”. I can probably do another several runs and do proper benchmarks if anyone is interested.
My questions are:
- Did anyone else notice this? I mean would you consider restic over SFTP slow?
- What can be done to improve the performance? Is this a limitation of SFTP protocol and/or restic repository format?
- What other protocols could be used that have better performance? I’d prefer something with encryption while on the wire. And I’ll be using this over network with my hosting provider, so something that works fine with high latency would be nice. EDIT. I mean I can start some S3 storage server or HTTP server on my backup machine if that helps and it’s faster than SFTP.
