I am recieving the follwoing error when trying to recover a file. could any one tell me what is meant by salvaging a volume....


Starting file recovery...
frecover(2105): did not find expected file marker
frecover(5409): unable to read volume header
frecover(5418): not an fbackup volume; unable to read volume header
frecover(2105): did not find expected file marker
frecover(5412): Do you wish to try to salvage this volume? (^[yY]/^[nN])

It appears that this is not an fbackup tape.

How was this tape written. Was fbackup used or was something else used?

[Bill Hassell]

fbackup reads the first record on the tape to see if it is an fbackup tape. Rather than just reject it, the program assumes that there may be some minor corruption in the header. So if you say yes to salvaging the volume, it will try to skip forward and see if there is anything recognizable. However, the most likely cause is that this tape has been written by another backup program such as tar or cpio.

the tape was used by data protector 5.1. After that I have used it for fbackup.

I have tried taking the backup on this 2-3 times however whenever I do reovery it shows the same message.


How to clean header information ?????????

Hi,

fbackup shall be able to overwrite on any protected media of DP. Was that fbackup successful?

You can even use other commands to try overwriting this media like tar,cpio or dd. But these will overwrite any current fbackup/DP data in the media. Try one of these

#tar -cvf /dev/rmt/?mn /tmp
or
#dd if=/dev/null of=/dev/rmt/?mn bs=2048k

Where /dev/rmt/?mn is you tape device file.

HTH,

yes the backup secission was successful, I have tried this for 2-3 times.. However after salvaging the volume the files are getting recovered also.

But at the first place why is it asking so, is what that is annoying me up.
