You can back up the
PowerScale cluster data through version 3 or 4 of the NDMP protocol.
OneFS supports the following features of NDMP versions 3 and 4:
Full (level 0) NDMP backups
Incremental (levels 1-9) NDMP backups and Incremental Forever (level 10)
NOTE:In a level 10 NDMP backup, only data changed since the most recent incremental (level 1-9) backup or the last level 10 backup is copied. By repeating level 10 backups, you can be assured that the latest versions of files in your data set are backed up without having to run a full backup.

NDMP TAR backup type
Dump backup type
Path-based and dir/node file history format
Direct Access Restore (DAR)
Directory DAR (DDAR)
