Cartridge Overwrite protection confusing
Need to clarfy something in my mind about BE overwritte protection issue...
I've a BE2014 and a connected LTO tape. The cartridge capacity is 400GB. I need to backup 200GB data daily and want to use cartridge capacity with maximum efficieny. This is my scnerio;
- 1'st Saturday : I use a blank media and backup 200GB to the media (remained 200GB)
- 2'nd Saturday: I run another backup job and append 200GB additional data to the media (no more empty space)
- 3'rd Saturday: I run another backup job 200GB. Overwrite protection is 0. Also it's set as "Append to media, overwrite if no appendable media".
Could you please tell me which data will be overwritten; 1'st Saturday or 2'nd Saturday? Of course we normally want to overwritte the 1'st Saturday data. What is the behaviour of BE and how can I control its behaviour?
