Files not overwriting
Once again, let me say that I am new to Backup Exec. I have all of our servers backing up to 2 different storage devices. I believe I have the backup jobs set up identical to each device, however I am seeing one main difference between the files on the devices. The one device never gets full, it always maintains about the same amount of free space. The second device always gets full, I have to go in and manually delete the files so I do not receive failed jobs. My first thought is that I did not have the media sets set up correctly, so I created a new media set. I specified that I wanted the data to append and overwrite in 45 days. However with that said and done I still have files from more than 45 days ago. I want this device to be self sustaining like the other device.
The second thing that I need is some advice... What is the ideal size for back up files? I have just taken over the back up's for the company I work for and they had the file size limit set from any from 1 GB to 999GB. I always thought 4 GB was a good limit, although I am guessing that it should also be dependent on the amount of data in which you are backing up.
I would appreciate some input on these 2 questions. Thanks for your time.
