Deleting Redundant Time Machine Backup v2

Hello,

After recovering failed btrfs due to a hard reset (many thanks again to StephenB!) I ran into issues with TimeMachine backups. I am looking to remove the old backups (this was very helpful https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Deleting-Redundant-Time-Machine-Backup/m-p/1797886/highlight/true) but am not sure which path I need to include in the following ssh command

# btrfs subvolume delete -c /path

I thought it should be /data/.timemachine, but it does not seem to work. The subvol list/data gives the following for TM

 

ID 265 gen 886902 top level 5 path .timemachine

 

TIA

    If you are wanting to delete all the backups in the .timemachine folder, you should be able to just navigate into it and delete the the backups there (leaving .timemachine itself alone).

     

    I'm not a mac user, but I believe you should also be able to delete the backups from the mac.

      Since losing the btrfs file system, I am getting error messages when trying to connect to the folder using smb. I figured my best bet would be to delete all prior backups (I have 1 actually) and then reconfigure the TM from scratch.

        One way to as access the full NAS data volume (\\nas-ip-address\data ) using the NAS admin credential.  .timemachine is a hidden folder, so you would need to enable viewing that.

         

        With ssh, you'd enter

        cd /data/.timemachine

        to navigate into the .timemachine folder
