DB2 Backup Naming convention

I had a hard time finding this on the internet, so I thought I'd post after I found it in a book.

The naming convention for a DB2 file system backup will be:
Alias.Type.Instance.Node.Catalog_Node.MonthHourSecond.Sequence
Example:
MyDB.0.DB2INST.NODE00000.CATN0000.20131015131259.001
   ↑       ↑        ↑                ↑                   ↑                ↑   ↑  ↑     ↑   ↑     ↑
Alias     |    Instance          |           Catalog Node     |    |   |      |    |      |
       Backup Type       Node                              Year  |   |      |    |      |
                                                                            Mon  Day  |  Sec   Seq
                                                                                           Min

backup Db2- unable to force applications

When trying to backup a db on db2 LUW 9.5, I get the following message, even after running quiesce.

SQL1035N The database is currently in use. SQLSTATE=57019
 
There is some good advice involving authority here: http://www.dbforums.com/db2/1663529-backup-db2-unable-force-applications.html#post6596923

However, it did not apply to my situation.

In desperation, I decided to just restart the instance.
When I did, I got an error indicating invalid credentials.

I had to go into the Windows Service and change the password for the user.
That cleared up the issue.

Whaddya know...
