Cookbook Procedures

Selecting a Tape Drive

We suggest using an 8mm tape drive on beetle for <10GB of data; use the DLT7000 on bao2 or the mammoth2 on beetle for more capacity. Click here for more information.

Each tape drive has its generic name written on it (eg, tps3d4.8500c). The tape name you will actually use is derived from the generic name; in this case, it will be /dev/rmt/tps3d4.8500c -- note that /dev/rmt/ is prepended to the generic name.

For this example, we will assume that you are using the 8mm tape on beetle whose generic name is tps3d4v.8500c.

Creating a Tape Backup

Assume all the files you want to back up are located in a single directory tree, eg, /srv/temp/projectx and its subdirectories. This procedure will create a log file listing all the files copied to the tape.

• Load your tape cartridge into the tape drive labelled tps3d4.8500c.
• Log onto beetle.
• beetle> cd /srv/temp/projectx
• beetle> tar cvbf 64 /dev/rmt/tps3d4.8500c . >& ~/projectx.tarlog
• After the backup is complete:
  • eject the tape.
  • Label the tape with the date, the data stored (projectx), and the tar command used: tar cvbf 64.
  • write-protect the tape
  • put tape back in the drive and list contents to verify tape can be read
  • (optional) Print your logfile ~/projectx.tarlog
  • eject and store tape along with the printout of your logfile.

Listing the Contents of a Tape Backup

Assuming the same tape drive in the previous example:

• write-protect the tape and load it in the tape drive
• Log onto beetle.
• beetle> tar tvbf 64 /dev/rmt/tps3d4.8500c

Restoring a Tape Backup

Assuming you are using the same tape drive in the previous example, and want to restore the tape files to /srv/frames/myfiles/:

• write-protect the tape and load it in the tape drive
• Log onto beetle.
• beetle> cd /srv/frames/myfiles/
• beetle> tar xvbf 64 /dev/rmt/tps3d4.8500c
