Choose a snapshot dir and copy back either to =/t3home/$USER= (or =/work/$USER=) what you need by =cp= command. ---+++ /t3home example: <pre> $ cd /t3home/$USER/%BLUE%.snapshot%ENDCOLOR% $ ls daily.2019-02-26_0010 daily.2019-02-27_0010 monthly.2019-02-01_0010 weekly.2019-02-24_001 </pre> ---+++ /work snapshot location example Since October 2019 there is an option for user to create a snapshot of workspace. Please contact administrators for more information. <pre> $ cd /work/$USER/%BLUE%.zfs/snapshot%ENDCOLOR% [martinelli_f@t3ui01 ~]$ cd /work/$USER/.zfs/snapshot [martinelli_f@t3ui01 snapshot]$ ls -l dr-xr-xr-x 1 root root 0 Dec 10 18:44 zfssnap-day-20161207-011142 <-- Max 2 past days dr-xr-xr-x 1 root root 0 Dec 10 18:44 zfssnap-day-20161208-014735 </pre> In a case of =/work= please be aware regrding deleted files that are still referenced in snapshots. In that case deleted files are saved in snapshot. And snapshot grows in space correspondingly. This affects your =/work= space quota while snapshot is a PART OF QUOTA. Till snapshot itself is deleted you won't not get a free space . Over quota running often means that you're frequently adding/removing big files in your =/work= . Instead please stage data to UI/WN =/scratch= or the =/pnfs= areas for that purpose! <!--Your =/work= usage is published here: http://t3mon.psi.ch/PSIT3-custom/space.report -->
