Backup Exec 2012 - Media Set advice
I am setting up media sets for our backups. We currently backup as follows:
- Monday: Incremental
- Tuesday: Incremental
- Wednesday: Incremental
- Thursday: Incremental
- Friday: Full
- Saturday: Incremental
- Sunday: Incremental
These backups are backed up to disk and retained for 4 weeks, plus duplicated to the DR appliance (we have two 3600 R2 appliances). This allows us to restore from any day in the last 4 weeks from disk.
We also have a requirement to retain 6 months worth of backups. We have an LTO5 tape library connected to our CASO DR appliance and my next task is to configure the monthly backups. We would retain Month 1, Month 2, Month 3, Month 4, 5 and 6 for 6 months.
I have a couple of questions .
1. As I only wish to duplicate the monthly backups to Tape should I add a schedule to duplicate the full backup to tape the day after the monthly full runs? Presumably if I selected "Duplicate data immediately after source task completes" this would also duplicate the weekly backups.
2. What would be the best way to configure the media sets? As we have a 24 slot library I had thought one media set would be sufficient for the 6 months of backups, but from reading the admin guide and other resources I am unsure if that would be the right option as the append period would be need to last for 6 months. Would it be better to create a "month 1", "month 2" etc media sets and allow them only to append for a few days? If that was the best option would I then need to edit the job each month to select the correct media set?
Any advice appreciated, thanks. I've attached a screenshot of the current backup properties if that helps any.
