Will this work? Right now a cron job runs amdump every day of the week in the AM. I just forced amanda to do a full dump on Sat AM. I am leaving the tape out of the tape drive. The full dump image should go directly to my holding disk. Still leaving the tape drive empty, Amanda runs again on Sun AM. She should do an incremental - (yes?) and send that level 1 image to holding disk too (yes?). I should get Level 1 dumps on Tues AM, Wed AM, and Thur AM sent to the holding disk if I have the reserve parameter set up correctly and enough room on the holding disk. (yes/no?) *Then on Friday AM I will amflush everything in the holding disk to tape. The holding disk should have a full dump image and a weeks worth of incrementals. Do you think this will work? Right now - I have the reserve parameter commented out in my amanda.conf. Should I set it to 50 %?

Either that or have the fulls left in the holding disk too (which will require tweaking reserve) and have them amflushed to tape along with the incrementals. -- Alexandre Oliva Enjoy Guarana', see http://www.ic.unicamp.br/~oliva/ Red Hat GCC Developer aoliva@{cygnus.com, redhat.com} CS PhD student at IC-Unicamp oliva@{lsd.ic.unicamp.br, gnu.org} Free Software Evangelist *Please* write to mailing lists, not to me Date: Mon, 13 Nov 2000 13:23:00 -0500 [EMAIL PROTECTED] Wrote: >Not sure if you caught the discussion about this with Jean-Louis, >Alexandre and I, but apparently the bump parameters being set to zero >will not do what I thought in the absence of tape, but Jean-Louis thinks >that if you just set "reserve" to anything smaller than 100 (e.g. 99) >in your holdingdisk definition, it will start bumping. >To answer your next question before you even ask it :-), the "reserve" >parameter was put in for sites like yours who want to run without tapes, >putting the images just into their holding disk.
