Because if you don't have backups, it's not a question of "if" your data will get lost, but "when." Remember, data loss is like a bad salsa dancer - no bueno!
DDS was developed by #HP and #Sony at the end of the 1980s, based on the DAT format. It was primarily used for backup storage.
The DG90P pictured here is a DDS-1 tape that can store 1.3GB (up to 2GB compressed). In 1990, the usual hard drive capacity in a personal computer was less than 100 MB.
So, what better day than today to check if the tape drive is working, then make a backup of the #HP 715?
HP-UX comes with an integrated backup tool called #fbackup. This is a command line utility but SAM, the System Administration Manager, has a graphical interface to help prepare, then start an interactive backup session.
And since no backup is valid unless the restore procedure has been tested, let's restore a file from our freshly made tape.
If you didn't know, #HPUX also comes with this pretty nifty tool called Ignite-UX. Although not included in the default "Core OS" installation, it can easily be added from the Application Software CD-ROM.
Ignite-UX can create a bootable recovery media that integrate the entire HP-UX installer. It's like creating a new installation media, but with the content of your already configured system.
