Shell Programming and Scripting

Hi All,

Can anyone tell what this script does?

I have a webserver linux box. The tech has left the company and never tell us if the backup tape is running or not.
I'm newbie to linux and try to investigate if we have backup running or not.

I did run : "mt -f /dev/tape status" command and the result is:

SCSI 2 tape drive:
File number=28, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x40 (no translation).
Soft error count since last status=0
General status bits on (81010000):
EOF ONLINE IM_REP_EN

I try to see what files has been backup up. But because i'm a newbie, i don't know how to find it.
I did some reading and some poeple use "TAR" method. But i don't think my webserver uses "TAR" method.

I found this script below on "ROOT" folder. Not really understand

#!/bin/bash

/sbin/dump -0ua /backup
/sbin/dump -0ua /var
/sbin/dump -0ua /home
/sbin/dump -0ua /
/sbin/dump -0ua /logs
/sbin/dump -0ua /boot


Please help me I'm stuck

See man dump and man restore for information about those commands. You can use mt -f /dev/tape rewind to rewind to the beginning of the tape, and restore -t to check the contents of the tape.

Since the tape is on "file number 28", it gives me the impression that the tape is never rewound, and the backups are just appended each time. You might want to check how many backups your tape has room for.
