NOTE: You cannot restore an OSS file that is larger than approximately 2 gigabytes to a system
running an RVU that does not include support for OSS large files.
Creating a pax Backup of OSS Files in the Guardian File System
If the output of a pax backup is less than 8 gigabytes (for J-series RVUs or for H06.06 and later
RVUs) or less than 2 gigabytes (for RVUs prior to H06.06), you can create the backup in the
Guardian file system. If a fileset backup requires more than the size limit of a pax archive file, you
can either:
• Back up sections of the fileset (each section must be smaller than the size limit of a pax archive
file).
• Compress the pax archive file. However, a compressed pax archive file can only be restored
from an OSS shell; the PINSTALL command cannot correctly process a compressed pax
archive.
To determine the size of the backup for an OSS fileset, assume that the backup requires as much
space as the fileset itself.
To determine the size of the HOME fileset, for example:
1. Determine the subvolume name of the fileset by obtaining its DEVICELABEL value from the
fileset definition. The last five digits in the Guardian subvolume name (which begins with ZYQ)
correspond to the DEVICELABEL value.
For the HOME fileset in this example, the DEVICELABEL is 000001, so this fileset’s subvolume
name is ZYQ00001.
