Implications of using AOFO

Created: 21 Oct 2013 | 6 comments

Hi,

I know AOFO is used when we want to backup files while they are in use (am I correct)?

I just wanted to know what are the implication of turning on AOFO?

for example I have several jobs wich end with exceptions on certain files skipped because they are use.

I can turn on AOFO or I can exclude them from the selection.

So is there any downside to using the AOFO feature?

Thank you

It is better if you use AOFO on files/folder backups. Having said this, if you are getting exceptions for files like Outlook .pst file, AOFO is not the solution. The .pst file would need to be closed from outlook before it can be backed up.

It is not recommended to use it on Agent based backups like Exchange.

So basicaly, if I use it for files/folder backups it should it doesn't have any implication on the backup process (time, job rate...), and it is suggested not to use it on machines that runs AD, Exchange, SQL etc...

Thanks

...the other option is to split your backups off from each other. Backup files and folders using AOFO, and backup DBs without.

You can follow my article below on how to do this:

If you choose to turn off AOFO and exclude the offending file, you would have to do this for each file that cannot be backed up.  Suppose FileA is opened during the backup and cannot be backed up, you would have to exclude it.  However, it might FileA is opened during that particular backup and is an important file which should be backed up.  If FileB cannot be backed up during the next backup, you would again have to modify your selection list to exclude FileB.  There is a lot of maintenance to this approach.

The rule of thumb for backups is: If in doubt, backed it up.  It is better to turn on AOFO and backup everything.

Thanks pkh,

Of course you are right, I was just asking a general question to understand the meaning of AOFO.

In my case I have several files in use everyday which are not necessary for backup so I was not sure about the best action to take.
