The purpose of this article is to share with you the example analysis of nbu 196errors and 191errors. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

NetBackup (NBU for short) is one of the best backup software in the world. It is an important enterprise backup and recovery software for heterogeneous platforms in the field of storage management of Symantec. The NBU platform provides unified data backup and recovery management based on disk and tape, protecting environments such as UNIX, Windows, Linux, and NetWare. From remote offices to data centers, from desktops to servers, from files to databases and even operating systems, NBU can provide comprehensive protection, while all functions are managed and implemented through a console, simple and convenient.

Nbu reported an error this morning with the following message:

NetBackup Status Code: 196

Message: client backup was not attempted because backup window closed

Reason: Drives are in use,No drives are available .

The NBU is followed by a tape drive. From 11:00 every night, more than 20 backup strategies are running at the same time. By the end of the month, there may be not much tape left, and there is a competition for resources among multiple backup strategies, resulting in individual backup policies being suspended without tape availability until the backup window ends. So there is nothing else in the system log but 196 superficial imagination. It is also possible that the backup policy has been turned off within the backup time limit, so there is no attempt to backup the client. To solve this problem, we can choose the strategy that needs to be backed up, and re-execute the backup through the restore job command when none of the other backup strategies are running during the day. Manual backups will ignore the backup time limit. Of course, in order to avoid this problem, we can also build a few more strategies so that different policies correspond to different volume pools.

There are also 191 errors, message prompt: no media is available. This error usually occurs near the end of the month, mainly because the tape is changed once a month, and the backup has basically reached the maximum capacity of the tape library by the end of each month, so this prompt tells us that the tape media is not enough. Once the tape has been replaced, there will be no more repeated errors.

The above is the example analysis of nbu 196errors and 191errors. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
