I’ve been using Restic 0.9.6 since Jan 2020 to backup 3.5TB from a Windows 2019 Standard Server to Minio running under FreeNAS. The two servers are connected with gigabit ethernet. The backup normally runs 3 hours and 45 minutes however on occasion it will run double that. All good.
Over the weekend I simply replaced restic.exe (0.9.6) with restic.exe (0.12.0) and last night the backup completed in 12 minutes!
Does this make sense?
