Backing Up User Files
-f archive-name
specifies the relative OSS pathname of the archive file to be read.
For example, to read the archive a.pax, with all files rooted in /usr within the archive
and extracted relative to the current directory, enter the OSS shell command:
pax -r -s ',^//*usr//*,,' -f a.pax
In this example, the expression:
',^//*usr//*,,'
translates into an ed replacement string as follows:
Creating a pax Backup of OSS Files in the Guardian File
System
If the output of a pax backup is less than 2 gigabytes (GB) long, you can create the
backup in the Guardian file system. If a fileset backup requires more than 2 GB, you
can do one of the following:
•
You can back up sections of the fileset (each section must be smaller than 2 GB).
•
You can 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.
