Home Directory

ITaP provides home directories for long-term file storage. Each user has one home directory. You should use your home directory for storing important program files, scripts, input data sets, critical results, and frequently used files. You should store infrequently used files on Fortress. Your home directory becomes your current working directory, by default, when you log in.

ITaP provides daily snapshots of your home directory for a limited period of time in the event of accidental deletion. For additional security, you should store another copy of your files on more permanent storage, such as the Fortress HPSS Archive.

Your home directory physically resides on a GPFS storage system in the Research Computing data center. To find the path to your home directory, first log in then immediately enter the following:

$ pwd
/home/myusername

Or from any subdirectory:

$ echo $HOME
/home/myusername

Your home directory and its contents are available on all ITaP research computing machines, including front-end hosts and compute nodes.

Your home directory has a quota limiting the total size of files you may store within. For more information, refer to the Storage Quotas / Limits Section.

ITaP maintains daily snapshots of your home directory for seven days in the event of accidental deletion. Cold storage backups of snapshots are kept for 90 days. For additional security, you should store another copy of your files on more permanent storage, such as the Fortress HPSS Archive.

Your home directory is medium-performance, non-purged space suitable for tasks like sharing data, editing files, developing and building software, and many other uses.

Your home directory is not designed or intended for use as high-performance working space for running data-intensive jobs with heavy I/O demands.
