I am running VB&R 220.127.116.117.
I must be missing something in how the Virtual Synthesized Full Backup for Tape process works. Reading the forums and talking support have only confused me further.
I run a standard 'Forever Incremental' with a 30 day retention. For offsite storage and archival purposes I use tapes in a StorageLoader.
My archival GFS rotation is pretty standard. Daily are retained a week, weeklies are retained a month, monthlies are retained a year, and yearlies are retained indefinitely.
My goal is to obviously have fulls on the weekly, monthly and yearly tapes, with incrementals Monday through Thursday.
Initially I created a single media pool with 1 week retention. I created a Backup to tape job where I scheduled a full Virtual Synthesized Full to run each day and of course I checked off "Process incrementals". I set both full and incrementals to run to the one media pool. This way, I had a full on each tape for taking offsite (including weekdays). That was my intent: the less tapes to drag around the better.
Week 1 seemed to run ok, but this week I ran into the issue where the .vbk from week 2 was written to tape along with week 1, similar to the issue brought up in tape-f29/writing-fulls-twice-in-a-row-t25750.html
I reworked my setup after that a bit. I created a "full" media pool (1 month retention) and an "incremental" media pool (1 week retention). I scheduled the Backup to tape job to run Virtual Synthesized Full Backup on Friday (so I have a weekly full) and then of course the incrementals would copy to tape on weekdays. The goal would be that the weekly full would be retained a month (so January week 1 would be retained and used as February week 1) and the incremental would be retained a week (so my Monday tape is reused the following Monday).
I have spoken with Support but only managed to confuse myself further on how this works and how I can ensure the corrrect vbk (and only one vbk!) and vibs are backed up to tape. I was hoping someone could help clarify this for me a bit and tell me if I am on the right track or whether I should be doing something completely different.
