Overwrite/Append Settings
I just want to make sure I have the correct handle on Overwriting and Appending media (Backup Exec 12).
I want to have 2 weeks worth of backups at a time, and then the 3rd week would overwrite the first week...and so on. There will be 2 full backups each week paired with incremental backups. I believe I need 3 jobs and 3 media sets scheduled as follows:
MEDIA SETS
Ovr13d_App0h
Overwrite = 13 days
Append = 0 hours
Ovr13d_App3d
Overwrite = 13 days
Append = 3 days
Ovr13d_App2d
Overwrite = 13 days
Append = 2 days
FULL BACKUPS
Tue, Fri
Overwrite
media set Ovr13d_App0h
INCREMENTAL BACKUP 1
Sat, Sun, Mon
Append, Overwrite if no appendable media
media set Ovr13d_App3d
INCREMENTAL BACKUP 2
Wed, Thu
Append, Overwrite if no appendable media
media set Ovr13d_App2d
Would the above method be the ideal way to do this, or is there a better way? Because the only other thing I can think to do is create 2 media sets (Ovr13d_App2d and Ovr13d_App3d) and schedule 4 jobs (2 full jobs and 2 incremental jobs). I'm not sure if that would have any advantage though...

Ok,
I broke out Excel and counted the days for my Full and Inc (based on my jobs starting at 6pm, 10-12 hr estimate for full, 2-4hr estimate for inc, and started counting when the job ends). I think I have a backup plan that should work using 2 media sets, and 2 jobs. The sheet is attached, and here is my outline:
Full Backup Media Set:
Opp = 11 days (Could even be 13, but 11 is all I need)
App = 0 hours
Inc Backup Media Set:
Opp = 13 days
App = 0 hours
My Full and Inc backup jobs are all set to "Overwrite". Then select "Use over writable media before scratch media".
This will give me the 2 week retention I want before overwriting. One the Third week, Tue overwrites the Tue from week 1. Then Wed overwrites wed from week1.
If someone can confirm this, or point out what is wrong with my logic, I'll give out some points... I might even increase them.

Well the objective here is to help not to get the points increased
now that u mention the points i guess the trouble is not worth 125 points
now that u mention the points i guess the trouble is not worth 125 points
The main point that u have not mentioned here is the number of tapes being used and what jobs are appending to which tape?
The reason I ask is when you append to a TAPE or a media the OPP is reset

Thanks for the replies. This is a backup-to-disk job.
that makes your task a lot easier.
How much space do you have for the B2D ????

Sorry
Forgot to mention
The MEDIA OVERWRITE PROTECTION LEVEL should be set to PARTIAL
Set the Jobs to OVERWRITE MEDIA when the job begins
Forgot to mention
The MEDIA OVERWRITE PROTECTION LEVEL should be set to PARTIAL
Set the Jobs to OVERWRITE MEDIA when the job begins
so if you have 2 FULLS you should create respective incrementals
Also the strategy that u have formed will not work the way you expect .
