Description Uri Simchoni 2015-10-29 22:30:10 UTC
When the snapshot files for a share are located outside the share's root dir, the previous version files cannot be accessed.

For example, suppose we have:
- a volume mounted at /myvol
- a share myshare at /myvol/myshare
- volume snapshots mounted at /mysnaps/@GMT-xxxx

Then the smb.conf for shadow_copy2 needs to be:

path = /myvol/myshare
vfs objects = shadow_copy2
shadow:mountpoint = /myvol
shadow:snapdir = /mysnaps

In that case the snapshot files cannot be accessed via the previous versions interface, because they are regarded as wide links.

It can be verified without actual snapshots by creating a suitable directory structure.
