the WbAdmin Windows 8 backup utility is not releasing file after backup finishes.
Posted on 2014-08-05
This is the first time I have used the Windows 8 wbadmin utility and I have a few questions.
My boss wants to backup his laptop once a week while alternating between two 4GB disks.
I intend to make a scrpt file that he can run manually.
it will start with two parts:
part 1 will be: <wbadmin start backup -backupTarget:E: -include:C: -allCritical -systemState -quiet>
Part 2 will contain logic that deletes any E: backup file that is over 12 weeks old except files created in the first week of the month will be kept forever.
Since each 4GB disk can hold about 25 full backups, the above simple logic will run almost 4 years before either drive fills up.
So, here are my questions:
#1. How can I force the wbadmin to release the lock on the external drive? After a recent test, I could not eject the external drive because it was in use. I was thinking of adding a taskkill command to my script, but it makes me a little nervous to kill the backup task so abruptly.
#2 The boss is supposed to close outlook before running the backup, but I suspect he might forget. I believe the above command will backup up Outlook PST files even if Outlook is open. Is that correct?
Please don't worry about issues like in flight database updates, or even losing one or two eamils. This laptop doesn't contain life or death data, just "normal" business records.
#3. I saw a forum post that explain that the first run of WbAdmin backups up the whole image, and that subsequent executions will run much faster because they only backup files that changed. I assume that means there will be an incremental change file for each run. How can I direct wbAdmin to always make a full image?
