In Backup Exec 2010, I have scheduled a daily incremental (?) backup job to back up files and folders (which is about 800GB) from E drive to an 3TB external hard drive with a hope that it will erase old data necessary to make room for new data automatically.
The very first job took about 12 hours. 2nd/3rd/4th job took about 7 hours consistently. Since there aren't that many files created or edited daily, I thought it would take less than 1 hour. Windows server backup that is done daily, which is incremental, takes less than an hour.
Apparently I did not set up this job correctly. It is already showing "low disk" on 3TB external usb HD.
I attached some screenshots from the backup job properties.
Can you help?
