backup performance degrade on extrenal disk
Hi,
My client is running backup exec 2012 on SBS 2011 and backup to external USB disk, I notice after a while the backup speed is degrade considerably, on full backup which normally takes 7 hours when it degrade it can take more than 2 days to complete for the same backup and sometimes it doesn't complete at all after several days, the full backup size is around 1TB. I do full backup on weekend and incremental during week days.
In the past what I do is format the external disk, and run the backup again sometimes is work out fine for sometimes after that; but I found if I have to format the disk after 2-3 times, it only last 1-2 weeks before I have to reformat again.
When I take out the drive in questions and plug to a pc and do copy of large files like movie, etc.. the performance seems to be ok.
In the past I use to use seagate external drive, the drives seems to last about 1 year before I notice this happen and replace it but about a years ago when seagate refresh their external disk the drives seems to be ok for about 3-4 months and we replace with western digital and seems to last around 3-4 months as well; I notice this issue with western digital last weekend.
I just wondering if this is backup exec issues? since when I test using windows copy seems to be ok.

Hi,
I think I found how to fix it after researching from the web, it seems check point restart for some reason cause the issue, I disable it last week, this week the backup seems to be ok.
