The only reason I can think of for using partitions in a tape library is to force BE to write to a particular tape or to a particular set of tapes.  This is a desirable outcome for some organizations.  However, this comes at a price.  When more tapes are needed and there is none in the targeted partition, BE will not be able to get the tapes from another partition even if they are available and the job will fail.  Backup job failures are bad for the organization.  The reasons why this is so are covered in the second paragraph of my article

 https://www-secure.symantec.com/connect/articles/must-mondays-backup-be-monday-tape

If the library is not partitioned, then BE can get a tape from another media set and complete the job.

BE will only take a tape from another media set if there are insufficient tapes in the targeted media set. ...

When your backup job failed with an error message, "Unable to connect to resource .....", you should expand the job log by clicking on the Expand All button and examining each of the resource that was backed up.  Do not rely on the resource given in the "unable to connect" message.

My BE media server is also my Lotus Domino server.  A couple of weeks ago, my job failed with "Unable to connect to resource C: drive".  This message makes no sense because the C: drive on my media server can definitely be accessed.  Otherwise, BE will not be able to run.  I ran a test to backup the C: drive and it did not fail, but the following night's backup again failed when it is unable to connect to the C: drive.  It took a couple of failure before I expanded the joblogs and saw that the C: drive backed up fine, but the Lotus Domino databases were not being backed up.  I realised that the jobs were unable to connect to...

BE comes with a commandline line applet called BEMCMD.  This program is located in the BE installation directory, along with it manual.  One of the BEMCMD can be used to start jobs which were already created.  For example,

"C:\Program Files\Symantec\Backup Exec\bemcmd.exe" -o1 -j"Backup SQL Logs"

Backup SQL Logs is a job that has been submitted as Run Now and On Hold.  The full path is used above because the BE installation directory is not in the default path in Windows.

You can schedule BEMCMD to run at a particular time using the Windows scheduler or as a pre- or post- command in a BE job.

In the example above, when the backup job ends, Backup SQL Logs will be started.  In this way, you can chain jobs together.

You can also run BEMCMD from any Windows machine...

Q.  I know I did the backup, but the data is not displayed when I try to restore it.

A. You got to ensure that the Beginning Backup Date and Ending Backup data are set wide enough.  See the diagram below

 

This is applicable to situation whether the backup is an old one or the server date is wrong.

Q. Can I delete an item from a backup?

A. No.  It is not possible to delete an item from a backup.  The only way is to restore the entire backup, delete the item and then backing up the rest of the data again.

Q. Why did BE use tape from a media set which is not targeted by the job?

A. When BE needs a tape to write to, it will first search for it in the following media set in the sequence listed below

1) the targeted media set

2) the scratch media set

3) any other media set

This is by design and is to ensure that the job completes successfully.

This problem will not occur if the Overwrite Protection Period (OPP) of the targeted media set is set correctly.  The most common mistake is not to cater for the time the job needs to complete.  The OPP starts from the end of the job, not the beginning.  Suppose the OPP is set to 1 day.  If your daily job is set to start at 10 p.m. and it takes an hour to complete, then the tape will be write protected until 11 p.m. the next day.  When the job runs again tomorrow at 10 p.m. the tape is still write-protected.  If the OPP is set to, say, 22 hours, then...

Attached is a whitepaper on how hardware encryption is done for LTO4 tapes.  Hardware encryption is part of the specs for LTO4 tapes.  Thus it is not available for LTO3 tapes although LTO4 tape drives can write to LTO3 tapes.

The part that I find particularly interesting is how an encrypted LTO4 is protected against low level copying.

Roadmap_August 2009.png

According to published plans, the all-conquering LTO tape format has no future after LTO 6, which is expected in 2012. This is ridiculous and there must be a secret roadmap for LTOs 7 and 8.

The LTO tape format dominates the open systems tape business, is used increasingly by supercomputer customers and is making some inroads into the mainframe area via bridges such as those from Luminex or Fujitsu's CentricStore (ETERNUS CS) virtual tape library (VTL). Supercomputer users like Argonne and NASA Ames in the USA will have ten year roadmaps. They can generate 8PB or more of data a year and there is simply no alternative to tape for...
