Considerations for file restoration with non-NetBackup restore utilities (on UNIX)
When you restore files with non-NetBackup restore utilities, be aware of the following considerations:
The file restoration procedure with non-NetBackup utilities does not apply to the encrypted backups that use NetBackup Encryption. Encrypted backups are recoverable. However, the backups cannot be decrypted.
To determine if a backup is encrypted, run a non-NetBackup restore utility such as tar -t before the recovery. The output for an encrypted backup is similar to the following example:
erw-r--r-- root/other Nov 14 15:59 2014 .EnCryYpTiOn.388 -rw-r--r-- root/other Oct 30 11:14 2015 /etc/group.10-30
Where the e at the beginning of line one indicates that the backup is encrypted. (Additional messages appear during recovery.)
The file restoration procedure with non-NetBackup utilities does not work on the Solaris platform. You cannot use /usr/sbin/tar on Solaris to read NetBackup backups. The Solaris tar command uses the ctime and the atime fields differently than other tar commands.
When /usr/sbin/tar is used to restore backups, directories with large numbers are created at the top level. These directories are from the ctime and the atime fields being read as pathnames.
You can use /usr/openv/netbackup/bin/nbtar to read the backups on Solaris platforms.
Steps 1 and 6 from the file restoration procedure with non-NetBackup utilities are optional in a standalone environment. If step 1 is skipped, DOWN the drive and then substitute the /dev path of the drive in place of /tmp/tape in the other steps. Remember to UP the drive when you are done.
