Appending Question

[chosen1]

I'm using Arcserve2000 on Windows2k with a Dell Powervault 128T LTO Library.

I want to create a job where:
- Backup Method is Incremental
- Every Monday is Full Backup with mode overwrite
- Tuesday is Incremental with mode Overwrite
- Wed- Friday is Incremental with mode append

I can't recycle tapes because of an executive order. So I want to minimize the number of tapes I use but at the same time make it easier to restore. Which is why I need every Monday to be a full backup, so the next 4 days can increment from there.


My question is:
- The Monday tape is a full backup which fills up the whole tape. Tuesday will use a new tape. Regarding Wed to Friday, is it going to append to the Tuesday tape? Or is Arcserve going to look for a new blank tape?
Thanks

create a custom rotation job (non-GFS) choose the 'Five day weekly incremental full backup on Friday'.
On top of the rotation rules section there is a separate selection for 'overwrite' or 'append'. Choose 'append.
In the rotation rules you can see how ARCserve wil behave using this rotation. I think this is what you want to achieve

hope I'm clear

Thanks, i created it.
It created a media pool with a 6 day retention.

I'm wondering if it will move the 2nd tape to the save set after Tomorrow's backup. So what will happen on Wednesday when it would need to append those sessions? Will it request for a new tape or will it use the 2nd tape...

It will move the second tape to the scratch set, according to the retention criteria (check the media pool properties for these criteria).
Appending to media is always allowed, regardless of the tape is in the 'save' or 'scratch' set. When the tape is full ARCserve will search for a second tape with the same name and random id with sequence #2, if this cannot be found it will search for a blank tape.
