Recently，I found a strange question on the NetVault Backup:Sometimes the Library was lose,and Backup Status:No Suitable Drive or Media Available.
The log didn't have errors,just warning like that:No Suitable Drive or Media for job xx instance xx.The detail,you can see the attachment.
Somedays ago(for one year),every job was right to backup,I didn't know how to happen this problem.
Dose someone know the problem?
The NetVault Backup version:8.51, build number 16
