DMF and archiving

Projects can apply for archive storage space. Archive storage spaces for projects are separate folders on Lustre under /project/archive. DMF handles the policies that are in place for archive storage spaces and is backed by a Spectra Tfinity tape library.

Policies for archive storage spaces:

• migrate files that are at least 100MB, older than 1 hour, and have not been migrated yet (check every two hours)

• release blocks in the filesystem for files that are already on tape and older than 4 hours (check every two hours)

Note

Released blocks do not count towards your block quota.

Warning

Released blocks do not have an effect on your available Inodes.
