After a hard disk failure I had to restore a one day old backup. After activating the desktop sync client, new files on the local computer were deleted.
Steps to reproduce
1. Sync your data from local computer
2. Create a full backup of owncloud server according to manual
3. Create some new files on local computer and sync them
4. Restore server from the backup of step 2
5. New files of step 3 will be deleted when running sync client after restore
Expected behaviour
New files of step 3 should be synced to server in step 5
Actual behaviour
New files are deleted
