I am using SFTP with Hetzner (yes, I know S3 would probably work better, but that would be another post).
Every know and then I read in server logs:
d’oct. 01 14:57:33 server kopia[2091958]: ERROR connection closed: unrecognized error when opening SFTP file /backup/kopia/kopia.repository.f: connection lost, will retry
d’oct. 01 14:57:33 server kopia[2091958]: ERROR error closing active connection: error closing SFTP client: EOF
I know this host limits connections to 10, so I suspect this is the problem. Is there a way to limit connections?
Reading kopia --help-long there is a
--num-storage-connections=NUM-STORAGE-CONNECTIONS
Number of storage connections
for repository validate-provider
, but I don’t think it applies to repository connection.
