Tar not able to perform backup on tape drive
 

My System is running with single Hard disk 9GB and I want to take backup of 3 GB data on tape drive. Free space available on server 900 MB.

I am using following command to perform the backup

tar cvf /dev/rmt/Sc0s0 source directory name

When I start backup by using TAR command the LED of tape drive start
blinking but no data backup done, during this process a image creation of
backup start on hard disk as a result system stop working and after deleting that image file system starts woking.

Please advise what can be done in this case..

Split the data into 500MiB blocks and back them up separately ... you can add each block into the tar archive as you go. (I take it you can back up smaller sizes?)

Of course, you know that your best solution is to find a bigger HDD. Old computers are good for this... you can sometimes get an extra 8-12GiB free or ultra cheap if you don't want to pay for a new one.

Thanks Simon...I would like to go for an extra HDD.
