I am currently attempting to configure our backup server using Backup EXec 2010 R2 and need a little help with setting up the correct method for my media sets.
Basically I would like to implement the following backup strategy:
>> Full Weekly Backup : Schedule Every Saturday except first Saturday of Month : Keep Data for 4 Weeks
>> Differential Daily Backup : Schedule Every Day : Keep Data for 1 Week
>> Full Monthly Backup : Schedule First Saturday of Month : Keep Data for 1 Year
>> Full Yearly Backup (Keep Forever) : Schedule Last Day of Year : Keep Data Forever
I am a little confused on what the best append and overwrite periods I should use for each policies media set.
I would like to keep my backups together, e.g. Mondays daily backups on separate tapes to Tuesdays daily backups. THe weekly backups not on the same tape as the Monthly or daily backups etc. etc. Is this possible, and if so how do I go about doing this? Or is this not good practice?
Due to hard disk limitations we are currently attempting to backup all data to tape except the Differential Daily backups, which are backed up to disk and then duplicated to tape. We are using LTO3 400/800GB data cartridges with 21 slots available and two drive devices. However, we have just ordered 22TB of disk storage space and I would like to hear your views on how I should set it up for backup straight to tape and backup to disk and then duplicated to tape...
Your advice and time on this would be greatly appreciated.
