Unexplainable Exceptions

Hi All

We are having problems with 2 of our clients with BE 2010 R2 Small business server suit. Both the servers run on Microsoft Small Business server 2008.

All this started couple of weeks ago and till then there were no errors but suddenly following exceptions appeared under the job completion status.

Exception-01

Backup- (Server Name)\MICROSOFT##SSEEV-79-40960-37914 - Database WSS_Content is configured to maintain transaction logs.  Transaction log backups are not being performed.  This will result in the log growing to fill all available disk space.  Regular log backups should be scheduled or the database should be changed to the simple recovery mode.

Exception-02

Backup- WebApplication\Content-DB 1 (Server Name)\MICROSOFT##SSEE\SharePoint_AdminContent_d4e397f2-a27a-48a0-a628-d25db6672bab)V-79-40960-37914 - Database SharePoint_AdminContent_d4e397f2-a27a-48a0-a628-d25db6672bab is configured to maintain transaction logs.  Transaction log backups are not being performed.  This will result in the log growing to fill all available disk space.  Regular log backups should be scheduled or the database should be changed to the simple recovery mode.

Exception-03

Backup- SBS SharePoint\Content-DB 1 (Server Name)\MICROSOFT##SSEE\ShareWebDb)V-79-40960-37914 - Database ShareWebDb is configured to maintain transaction logs.  Transaction log backups are not being performed.  This will result in the log growing to fill all available disk space.  Regular log backups should be scheduled or the database should be changed to the simple recovery mode.

On the other server we get similar errors but all errors are related to SQL Transaction logs not being backed up. On both servers  all the databases are  backed up and its configured to do a Full backup on all SQL/SharePoint databases.

In addition to the above we get the following exception on both the servers and on both its identical.

Backup- System?StateVSS Snapshot warning. File c:\windows\system32\drivers\damirr.sys is not present on the snapshot.

We also started getting the following email alert , again same for both servers.

Job Completed with Exceptions1 files were skipped.

Note:  The backup job was configured to use the Advanced Open File Option.  However, files were skipped during backup processing.  Please ensure that the Media Server SH-SBS01 is properly licensed with the Advanced Open File Option, or that the job is properly targeted for media servers that are licensed with the Advanced Open File Option.

We checked and AOFO is properly installed and licensed.

Not sure if this is related or not but it seems all this started after installing the Update HOTFIX 159293

For 1,2 and 3 refer http://www.symantec.com/docs/TECH126063

For this Backup- System?StateVSS Snapshot warning. File c:\windows\system32\drivers\damirr.sys is not present on the snapshot.

Search for damirr.sys on your system and put it in the location c:\windows\system32\drivers. BE is trying to back it up but not not able to find in the location but it might be there in the registry.

Job Completed with Exceptions1 files were skipped.

Note:  The backup job was configured to use the Advanced Open File Option.  However, files were skipped during backup processing.  Please ensure that the Media Server SH-SBS01 is properly licensed with the Advanced Open File Option, or that the job is properly targeted for media servers that are licensed with the Advanced Open File Option.

what kinf of files are missing, is it some database files or flat files. If it is database files then make sure those are only backed up by proper agent. Symanted recommend not to take snapshot backup for the database files

Hi Sazz

Many thanks for your reply. I never knew that there is such a requirement to backup the logs separately so will do as the KB says and get back to you later.

As for damirr.sys I m a bit hesitant to put it back on the System32 folder because may be this file got removed for a reason. So do you know any other way to rectify the issue?

Unfortunately the email alert or the backup logs does not give any indication as to which file it skipped from AOFO but it may be the damirr.sys because I can see the following  on the logs.

VSS Snapshot warning. File c:\windows\system32\drivers\damirr.sys is not present on the snapshot.

Do you think that Missing file and AOFO error can be related?

Yes you are getting this because 1 file is skipped (damirr.sys) and due to that you are getting this exception though it is not an error and you can ignore it if you want. This error is coming because the file might have removed but there migh be traces of this in the regsitry and when it tries to verify the same in the particular location it is not finding that file. So either make sure it is removed from registry or place that file at that location to avoid this error message. If you just put that file in that location it will not cause any issues as backup is just looking for that file to be there.

If you don't want to put damirr.sys back in that location, then create a dummy file with that name in the location, so that you would not get that error.

When you are backing up databases, you should not turn on AOFO.  Normally, we would have a separate job to backup databases and AOFO is off in that job.

Hi Sazz

Thanks for the clarification and the exceptions regarding the SQL/SharePoint databases are no longer there once I did a log file backup. I was under the impression that a full backup will do the transaction log s as well.Will try to put a dummy file as  Phk mentioned and let you both know what the outcome is.

Pkh, again i am under the impression that Exchange/SQL and SharePoint agents will take care of the backups and we do not need to worry about AOFO  since this is a BE SBS version but do correct me if I m wrong.

Symantec recommends not to use AOFO with database as it is for open files, if you are using the database agents there is no need of AOFO for the databases.

The use or non-use of AOFO is not dependent on whether you are having a SBS licence or not.  The SBS licence is a special bundle of licences which includes licences for Exchange, SQL and Sharepoint among others.

We normally have a minimum of two jobs: One with AOFO on for backing up flat files and the other with AOFO off for backing up databases, like Exchange, SQL, etc.

May be I did not made myself clear

When using agents for Exchange/SQL/SharePoint I thought we do not need worrying about AOFO even if AOFO is enabled for other flat files .Is that not correct?

Pkh, do you use tape s as the backup media? If so how do you schedule one backup to start soon after the other one finishes? 

Thanks

No. That is not correct.  When AOFO is enabled, it affects the whole job.

You would know roughly when your first job ends.  Schedule the second job to start about that time.  If it starts before the first job finishes, it will just queue for the tape and starts when it is free.  Alternatively, you can start the second job with BEMCMD.  See my blog below

Hi pkh

Many thanks for your reply and advise, always happy to learn  new things.

Another small question : when it comes to SQL/Sharepoint i guess we need to have 2 backup jobs , 1 for the database and other for transaction logs.Do let me know otherwise.

PS:Ignore the above.I just went through your blog post and BEMCMD seems an ideal solution to backup the logs.

For SQL/Sharepoint, you need a separate job to clear the transaction logs.

Ok Now we have the following configuration

1 data backup(AOFO) and 1 database backup(without AOFO) per day and  only on Friday another backupjob to backup the SQL/Shareoint Transaction logs(because SQL/Sharepoint is not being used frequently).

Another question:

Exchange databases reside on a seperate partition so

1.Do we need to backup the files on this partition during the data backup job in addition to database backup job

or

2.is it sufficent to backup the exchange using only the database bacup job

Thanks
