Lotus Nut

By default, BES debug logs are enabled at installation. They are not only enabled, but they have no roll-off time specified. I have seen this cause drive space issues (not to mention performance issues associated with so many heavily fragmented small files...)

To remedy this, you can open the BlackBerry Server Configuration and go to the Logging tab. From there, you will need enable the "Debug log auto-roll" and specify the number of days you wish to keep the logs in the "Debug log maximum daily file age" settings. In the example below, we will only be keeping 30 days worth of logs. After restarting the BES task and all of the BlackBerry Services, the files will be automatically purged.



Some notes:

You may just wish to restart the entire server instead of each of the individual services.

The daily folders will still exist, so do not panic if you still see them. They will exist because of three log files. By default, all BB phone calls are also logged. This is how your phone call logs get restored when you activate a new device. There are also some 2 SMS and PIN messaging log files. These are empty files by default, but administrators can enable this logging (without you being aware of it, by the way - you did know this, right?).

So go ahead and clean up your BES servers and try to remember to modify these logging parameters when you install the server (note to self...).

Several people have been blogging about using the (now-corrected) DAOS estimator tool. Feel free to add your savings calculations as a comment here or post them on your own blog!

Bruce Currier should be saving 49%!!
I had someone ping me with his results of saving 39%!
The third comment at Ed Brill's post on the Estimator tool reflects a 40% savings!
Almar Diehl blogged his results and will be seeing around 17% savings.

As demonstrated above, your mileage may vary with the savings...

A commenter at Bruce's blog (linked above) also noted that if you currently use a service to backup your mail databases offsite, then you should also be able to save a lot of money since you will be backing up much smaller NSF's.

And speaking of backups, make sure that you review the Backup and Restore considerations for DAOS!
