Append Period and Overwrite Protection Period
we have a very critical server and we want to take full and incremental backups regularly
Total Full backup size 400GB
Incremental would be - 15GB a day
i would like to reserve a media say (backup 004 tape) for this server. We have LTO-4 tapes with 1.6TB size 2:1 compression.
At the end of the week i need to have full data available for restore ,in the worst case scenario i.e., the server/hard disk goes
bad.
My scenario :
Saturday |
Sunday |
Monday |
Tuesday |
Wednesday |
Thursday |
Friday |

|
Full 12 am |
|
|
Inc 11pm |
Inc 11pm |
Inc 11-m |
Inc 11pm |
Please suggest me in this scenario.
You can change the setup or suggest a new one .Any help would be appreciated.
Assuming that you do not work on weekends (Sat & Sun), it would be better for you do to a full backup on Fri and then incremental backups on Mon. to Thu. There is no need to do an incremental on Fri. and then a Full backup on Sat.
You can set your AP to 7 days. Your Full backup job on Fri should specify ovewrite so that it will use a new tape and your incremental jobs should specify append so that they can append to this tape.
As for the OPP, it depends on how long you want to keep the tape. Set it accordingly.
