Restoring User Files
2. Use the File Utility Program (FUP) to rename the old security database files
and to move the restored copies to the correct subvolume.
3. Stop and restart Safeguard and all Expand lines to close the old security
database files and open the restored ones.
Restoring a pax Archive of OSS Files Directly From the
Guardian Environment
The PINSTALL utility that runs in the Guardian environment can restore a pax archive
backup made as described in Creating a pax Backup of OSS Files in the Guardian File
System on page 6-20 directly into the OSS file system.
At a TACL prompt, use PINSTALL to restore the backup to the OSS file system. For
example, to restore the $OSS.BACKUP.PAXHOME pax archive file, you would enter
the following command:
PINSTALL -pe -rvf /G/oss/backup/paxhome
Restoring a Compressed pax Archive of OSS Files From the
Guardian File System
The compressed pax archive made as described in Creating a pax Backup of OSS
Files in the Guardian File System on page 6-20 can be restored directly into the OSS
file system using the following OSS shell command:
zcat < /G/oss/backup/paxhome | pax -rv -pe
The zcat command uncompresses the file and sends the result to the pax command,
where the -pe flags preserve the file permissions.
Restoring Files From a pax Archive to the Guardian File
System
Because of the syntactic differences between the names of Guardian and OSS files,
the following behaviors can occur when a pax archive member is restored to a
Guardian file system:
•
An OSS filename might contain characters that are illegal in Guardian filenames.
As a result, the archive member cannot be created on the Guardian target and the
restore operation fails. For example, if the archived file were named
ca$h/.profile, then an attempt to restore it to /G/oss fails because of the
embedded dollar sign character.
•
In the name-transformation process, OSS names that are longer than eight
characters are truncated to the first valid eight characters. For example, the OSS
pathname abcde.fghi is transformed to the Guardian name ABCDEFGH. This
can cause confusion and make identification of files difficult. Filenames that are
similar in one environment might be transformed to the same filename in the other
environment, which might result in the overwriting of previously restored files.
