Sadly, it doesn't look like I'm going to get to revamp amvault the way I want to in this release. There's still hope, but release-blocking bugs are piling up at this point :( It really just needs to have pieces of taper glued on to pieces of amfetchdump. All of the supporting libraries are in place. Maybe someone else can take a look? If it's done right, then it will be able to double as an Amanda version of NDMPCOPY, which should be pretty cool.

Jean-Louis' suggestion looks enticing. Just one remark: as someone remarked in this thread, what happens the very first time amdump run with `strategy nofull'? The backup content is based on what since there is no full? What about amvault though? Is this still in the works? thanks! jf -- <° >< Jean-François Malouin McConnell Brain Imaging Centre Systems/Network Administrator Montréal Neurological Institute 3801 Rue University, Suite WB219 Montréal, Québec, H3A 2B4 Phone: 514-398-8924 Fax: 514-398-8948

I'd thought those settings where available as -o options on the amdump command. Single config with different lines in cron so nothing is edited or copied ? Maybe an amadmin force command once per week as well, just before the tape based run ? You can change the tpchanger with -otpchanger= , but changing a dumptype from command lines doesn't works with dumptype inheritance, it works only if it is used from the disklist, it is fix in SVN. But you can do the force full; and, if you have a holding disk of sufficient capacity, you can use -o to specify a non-existent tape device so that Amanda drops back and does incrementals only to conserve holding disk space. If you then flushed those out to a device, you could achieve what is being requested, I think. One objection to the original idea of having two separate configurations, is that to be running incrementals only, you have to have a full to reference. Within the context of that configuration, you wouldn't. I use a couple of different arrangements in different departments. In one department, their budget for tapes (or anything for that matter) is very limited. They also have less data to back up in the first place. I use -o on the cron line to define a non-existent tape drive and tape library during the week. Then, on Saturday evening, the cron let's it go to the tape library. Everything gets flushed to tape and the Amanda scheduler catches up on full backups. I'm not sure I even bother with the force full. The amanda.conf definitions are such that it wants at least one full every week and ends up doing them when it is finally given a chance. In most of my other departments, I run an ordinary backup every night of the week, and the Amanda scheduler distributes full backups through the week. Then, on the weekend I use -o in the cron to define a non-existent tape drive and library. So, on the weekends, I get incrementals only and they are all saved on the holding disk. On Monday night, those all get flushed out to tape with the regular backups. With this set up, my rotation of 35 tapes lasts 7 weeks instead of the 5 weeks I would get if I let it use a tape every night of the week. I believe this technique is documented on the wiki. -- --- Chris Hoogendyk - O__ Systems Administrator c/ /'_ --- Biology & Geology Departments (*) \(*) -- 140 Morrill Science Center ~~ - University of Massachusetts, Amherst --- Erdös 4

Re: 2 config, noinc and nofull
I never like using two configs. Recovery is complex. Why not use one config? amanda don't allow it, but you can cheat. Edit amanda.conf every days to change the tpchanger and strategy, if could be done by a simple script, or more easily, put the difference in separate file and use 'includefile', that way you just needs a 'cp' before each run. The only problem is with autoflush, if some dump are left on holding after a run, they can be flushed to the wrong tpchanger on the next run.

I'm planning to have on tape (LTO4) 3 or 4 sets of full backups, done once a week and have the rest of days doing incrementals only, to virtual tapes on disks. Obviously this will require 2 configs, the full one running only during the weekends with `strategy noinc' and another with `strategy nofull', done during the week days. Anyone has done so and/or have pointers/gotchas? Eventually when this is in production I will have to start doing offsite archiving with some sort of D2D2T so with that in mind, what's the status with amvault? I'd be more than happy to provide feedbacks while I'm still in testing mode. thanks, jf
