On TACC resources, how can I recover files I accidentally lost?

Note: After ten years of service to the national science and engineering community, the TeraGrid project has ended. It is succeeded by a new National Science Foundation (NSF) program, the Extreme Science and Engineering Discovery Environment (XSEDE). You should move any data stored on TeraGrid systems to an alternate storage resource. If you have leftover service units on your TeraGrid allocation, or if your research requires further use of high performance computational, visualization, storage, and network resources, consider applying for an allocation on one or more XSEDE digital services.

Depending on which file system the data resided on, it may be possible to recover lost data. Files on $HOME are tape archived regularly. Files removed from archive can also be recovered. Unfortunately, files that were lost on the high-speed parallel file systems such as $WORK are not backed up and are non-recoverable.

If you have lost files on $HOME or archive, send a file retrieval request to  help@teragrid.org . Please specify the date the files were lost, which files to recover, the location of the files, and the userid of the file owner.
