When I backup one particularly large site, the file backup does not complete most of the time.

I get this typical report

The site backup has failed with the following messages:
Files Directory backed up successfully to SEE-2012-12-09T22-46-28 in destination Backup SEE in 1658289.65 ms. 
Could not complete the backup because the script timed out. Try increasing your PHP max_execution_time setting.

I set max_execution_time to 3600
The backup size is around 20 GB

Another general backup by Virtuamin completes whithout any problem:
Backup is complete. Final size was 29.44 GB. Total backup time was 1 hours, 53:44 minutes

Is B&M inappropriate for such backup size?

Thanks

Reading again my post, I realize that the B&M message might be buggy
- it says it backed up "successfully" in 1658289.65 ms, while it did not, and I've seen in the backup history that the db backup scheduled at the same time proceeded one hour after the failed file backup, not half an hour.
I increased the php max execution time to 2 hours. I'll let know if the issue is actually a B&M notification mistake.
