Restic via ssh: chain multiple Restic operations with single ssh key password input?
Hello,
I use Restic to backup my laptop data to a remote server via ssh (not scheduled, I execute the script manually). I put everything in a bash script which does a sequence of restic backup, forget and check. I connect to my remote server via ssh with a key, and the key is password-protected (and I intend to keep it that way; I also want to avoid writing the password anywhere on file for obvious reasons). The problem I currently have is that when I run th script, I'm asked for the ssh password three times (once for each operation), but I don't know how long the backup operation will take (I usually execute the script in a shell and then minimise that window to carry on with my work) and if I wait too much to give the password again for the second operation once the backup is finished, the connection dies and I have to restart from scratch.
My question then is: is there a way to chain the three operations (backup, forget, and check) in a single restic input, so that I have to enter the ssh password only once? Other solutions that lead to the same result (with the password never visible in plain text in the cli or on file) are also well accepted. Thanks in advance for the help!
