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..
