File Management | HPC @ LLNL

LC supports a wide variety of file transfer protocols and tools, including FTP, NFT, HSI, SFTP, SCP, HTAR, Hopper, and give/take.
If you have multiple groups and/or resources that you manage together or you have a need to share data between teams, the IDM team can create a defined role (also called advanced role-based sharing) for your convenience.
See File Sharing and Transfer and Using LC File Systems for important usage information.
If you are a Tri-lab user, please see our Tri-Lab Distance Communication Transfer Tools page.

Green Data Oasis is a large data store on the unrestricted LLNL network.
It can be used for sharing very large amounts of data with external collaborators.

Globus is a file storage service with an endpoint in the LC green zone.
It can be used for sharing very large amounts of data with external collaborators.

Presently LC does not purge any of its file systems.
Temporary file systems (e.g. /var/tmp and aliases /tmp and /usr/tmp) are ephemeral. Data in /var/tmp is cleared at the end of batch jobs.
See Purge Policies and Using LC File Systems for details.

Home directories and a few other LC file systems and data are backed up for disaster recovery.
Temporary file systems are not.
For details, see Backups and Using LC File Systems.

User home directories, /p/vast/, /usr/workspace, /usr/gapps, and /usr/gdata have a read-only, online directory for user-accessible data recovery.
"Hidden" .snapshot subdirectory will not appear in ls commands
- You can cd .snapshot
- Contains multiple subdirectories, each containing a full backup and a timestamp when the backup was created.
