### HOME File System
### HOME File System
The HOME filesystem is an HA cluster of two active-passive NFS servers. This filesystem contains users' home directories `/home/username`. Accessible capacity is 25 TB, shared among all users. Individual users are restricted by filesystem usage quotas, set to 25 GB per user. Should 25 GB prove insufficient, contact [support][d], the quota may be lifted upon request.

The filesystem is backed up, so that it can be restored in case of a catastrophic failure resulting in significant data loss. However, this backup is not intended to restore old versions of user data or to restore (accidentally) deleted files.
