Hi all. I"m still reading through the BE 2012 admin guide so am learning this product as I go but one thing I read is that in order for the backup job to be able to esetimate the amount of data you have the back up, and the time it will take, you must enable Pre-Scan, which can only be enabled by turning on Test Run.
The very first time I did this, the server took as long to do the Test Run as it would a normal backup, many hours. If all this feature does is do some preliminary scans, why did it take that long? The amount of data was perhaps 1.7TB total, and the tape drive is LTO5.
Also can anybody advise me: is there a real-world usefullness for enbaling Test Run? I am assuming by enabling it, your normal backup jobstill runs but this Test Run poriton runs first. Or by enabling Test Run, are you converting your job from a real backup job to essentially a backup simulation but no real backup occurs?
Thank you.
