Hi,
I have a script in a customer site which performs a backup to tape and
then tries to verify the backup. This is my script:
#!/bin/bash
echo "rewinding tape"
mt -f /dev/st0 rewind
echo "retensioning tape"
mt -f /dev/st0 retension
echo "starting backup"
tar -cpf /dev/st0 --verify --files-from /root/scripts/backup.inc
--exclude-from /root/scripts/backup.exc
echo "rewinding tape & unloading tape"
mt -f /dev/st0 rewoffl
echo "finished backup"
But at the end of the backup I see:
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: /dev/st0: Cannot read: Input/output error
tar: Too many errors, quitting
tar: Error is not recoverable: exiting now
They have cleaned the drive, changed tapes but I always get the above
error messages.
Am I verifying the backup correctly or am I doing something wrong?
