You just might be in luck. Talapas does not currently NOT have backups, but it does take regular filesystem snapshots. These are located in /gpfs/.snapshots/ and are taken at the following times:
...
end of each week (before midnight on Saturday): weekly-{week # of month}
For example, to copy your deleted file from your project directory from last Friday:
[user@ln1 ~]$ cp /gpfs/.snapshots/daily-Fri/projects/myPIRG/myDataDir/path/to/myDeletedFile .
Your data may be accessible from within the snapshot, but once the old snapshot has been replaced by a new snapshot, data unique to the older snapshot will be gone.
Users are responsible for backing up their own data! Please see the FAQ below on how to transfer your files off of Talapas.
