Thanks Eric. https://github.com/rdiff-backup/rdiff-backup/releases/download/v2.1.2b2/rdiff-backup-2.1.2b2.win64exe.zip is working for for me on Windows 10, but I did encounter one slight surprise.
I've been running rdiff-backup 2.0.5 (from Powershell) to backup to a CIFS/SMB share on my NAS server mounted to my Windows machine. I access it using the path \\nas4free\finance-backup\Finance.rdiff-backup. For example: rdiff-backup-2.0.5\rdiff-backup.exe --list-changed-since 1B \\nas4free\finance-backup\Finance.rdiff-backup When I try to do the equivalent using 2.12b2 it doesn't recognize the backup repository. For example: rdiff-backup-2.1.2b2-64\rdiff-backup.exe list files --changed-since 1B \\nas4free\finance-backup\Finance.rdiff-backup ERROR: Path '/nas4free/finance-backup/Finance.rdiff-backup' couldn't be identified as being within an existing backup repository ERROR: Action list failed on step check However if I add an extra "\" at the beginning of the path it seems happy. For example: rdiff-backup-2.1.2b2-64\rdiff-backup.exe list files --changed-since 1B \\\nas4free\finance-backup\Finance.rdiff-backup Is the need for the extra "\" in 2.12b2 intentional?
