Accessing Synchronize __CYCLES folders with older snapshots on Synology via SAMBA

When synchronizing files onto a btrfs file system on Synology NAS devices and old states are kept as snapshot, then these snapshots are created as btrfs-snapshot through file system mechanisms. btrfs then mounts these snapshot on the root of the volume or subvolume. P5 preserves the snapshot in a __CYCLES folder on the synchronize target folder, on btrfs file system a soft link is created there that links to the actual snapshot. The P5 Restore section does not follow links and thus does not allow access to the snapshots via the __CYCLES folder in this constellation. Instead, it is possible to mount the share that holds the sync target folder (provided that is an SMB share). On Synology, SMB shares by default also do not follow soft links, but it is possible to change that: Enable the flag in the Synology Web GUI at Synology Control Panel -> File Services -> SMB section -> Advanced Settings -> Allow Symbolic Links within Shared folders After changing that and rebooting the Synology, the folders below __CYCLES become accessible via SMB. | |
