Why no option "remove the contents of backup destination" with backup to NFS?

I've setup my ReadyNAS 102 on version 6.10.3 to perform some backups to a Linux NFS server. The backups are set to run weekly and are full backups each and every time. After the first full backup completed, I expected to have the option to "remove the contents of the backup destination" for subsequent full backups (to ensure I'm not getting duplicates). Unfortunately, this doesn't seem to be the case (see attached image).

 

Any thoughts as to why this might be? Seems to work on CIFS\SMB shares, but not with NFS.

 

My NFS export is using the following options:

rw,async,no_root_squash

 

The backups are successful. I just do not have the option to remove the existing contents before executing a full backup.

 

Thanks in advance for any thoughts or help with this issue.

  • That is odd (and I've confirmed that on my own system as well).

     

    The option is there if the source is remote, and the destination is local - but not the other way around.

     

    If rsync is available, then that could be an alternative (giving you the "advanced" option to remove files that are no longer on the source).
