Re: How to do Incrementals
Its been said repeatedly on this list, that one of the hardest things to learn about amanda, is to trust it. We've been using it in our shop for years and it has *never* let us down. It will tell you through the reports it generates if you are asking too much of it so you can adjust the configuration, add tapes, whatever.
RE: How to do Incrementals
Dan, Why? Balancing incrementals and fulls across the entire dumpcycle is a feature. It reduces your risk (what if the full backup tape goes bad and you need to restore?) and allows you to get more backups in the same number of tapes. It allows you to just put in the next tape, instead of worrying about which set of tapes to pull from. It allows you to add more tapes to the set and have them used efficiently. Now, having heard all that, if you still really want to do it, there is a way. You will need two separate backup configurations sharing a common database. Configure one to always do full backups, and the other to do incrementals only. (Search the list archives for "incr-only" if you need more info.)

As has been discussed *many* times on this list, amanda works best when you let it decide when to do the backups (which, granted, is tough for all of us who are used to diligently planning the backup schedule). You *can* force amanda to do fulls only on the weekend (via amadmin force and/or separate configs), but it's really more trouble than it's worth. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
How to do Incrementals
OK, right now, I do a full backup every night. That's obviously not going to work forever ;). How can I run a full backup once a week and incrementals every day? Right now, my dumpcycle is set at 0 for everything. That makes it do a full backup every night, right? So, what do I need to set the dumpcycle to in order for it to run incremental? If dumpcycle isn't where I do it, then can someone help me out? Also, I thought I read somewhere that amanda would try to balance incrementals throughout the cycle or something like that. I don't want it to. I just want a full backup on the weekend and an incremental every night. Thanks! --Dan
