I recently upgraded from firewire to eSATA on a Windows 2000 server that backs up approximately half a terrabyte of data a day.
Using BackupExec, the time, predictably, is blazingly faster than firewire for completing this backup. When Windows Backup Utility is used to perform the same task, the time more than quadruples to barely faster than the firewire solution (14 hours versus 15 hours for firewire). BackupExec completes the backup in 4 hours.
BackupExec completes its backup in one single file, where as Windows makes about 450 1GB files when backing up. My immediate thoughts are that the extra retrieval time across the pci bus to create and retieve these files is the culprit, but that seems at worst a software issue and not alone enough to account for all the extra time.
Were this my personal computer, I would simply use BackupExec and be happy... however, this is a financial institution machine and the idea behind using Windows Backup is speed in rebuilding a network following a disaster... it's faster to use windows to retrieve a back up than to first have to find and install BackupExec before restoring.
Has anyone encountered this, or know the reason, or--hopefully--a solution?
Thanks for any help you can give in advance.
