That product is crap.. it has limitations.. or I dont know much about it. This is what I have found so far

1) you can not execute multipal backups at same time, backup must wait in que -- now considier u need to backup transation log file .. you are stuck cuz another backup is running..

2) Can not execute backups based on % log full. -- if you do you will end up with same problem as above.

3) extremly slow.

4) no gurantee backup will start as scheduled. it may be late cuz it is running on other servers.. or pervious backup is still exeucting.
