Step-by-step guide

Steps involved to restore $HOME Data 

  1. Access the Weka file-system  in question:

    cd /cds/home/<initial>

    Where initital is the first letter of your user-id

  2. Go to the .snapshot directory (e.g restoring data for user omarq)

    cd /cds/home/o/.snapshot

  3. Select the appropriate calendar date and time, the access point of the data is formatted as @GMT-YYYY-.MM.DD-HH.MM.SS (.e.g restoring data for omarq dated April 19th, 2021 at 6:00PM)

    [omarq@psbimmer ~ 13:52 Tue Apr 20]$ cd /cds/home/o/.snapshots/
[omarq@psbimmer .snapshots 14:05 Tue Apr 20]$ ls
