Hello list, I have a problem understanding the coherence between tape_splitsize and runtapes.
The Config: on my current system, i backup 2 disks with about 2 and 3 GB on DVD-RAM (like a virtual tape on hdd) It works fine, because the folders are smaller than 4.3 GB. Now i want to backup one folder with 5 GB and decided to test the tape_splitsize option. I set up a VM for testing: (Test Environment With Virtual Tapes) http://wiki.zmanda.com/index.php/Test_environment_with_virtual_tapes org "Acme Inc." mailto "[EMAIL PROTECTED]" dumpcycle 3 runspercycle 3 tapecycle 5 runtapes 1 dumpuser "amandabackup" tpchanger "chg-disk" # a virtual tape changer tapedev "file:/space/vtapes/test/slots" changerfile "/var/lib/amanda/test/changerfile" labelstr "TEST-.*" #label_new_tapes "TEST-%%" tapetype DVD_SIZED_DISK logdir "/var/lib/amanda/test" infofile "/var/lib/amanda/test/curinfo" indexdir "/var/lib/amanda/test/index" tapelist "/var/lib/amanda/test/tapelist" holdingdisk hd1 { directory "/space/amandahold/test" chunksize 10 Mb } define dumptype comp-tar { program "GNUTAR" compress none index yes split_diskbuffer "/space/amandahold/split" tape_splitsize 10 Mbytes fallback_splitsize 10 Mbytes record no # Important! avoid interfering with production runs } define tapetype DVD_SIZED_DISK { filemark 4 KB length 30 MB } I backup /etc in this example: du -sh /etc/ 48M /etc/ My virtual "DVD-Drive" have only 30 MB. Now the problem: if i try amdump test with runtapes = 1 the following error appears : FAILURE AND STRANGE DUMP SUMMARY: server /etc lev 0 FAILED [dump larger than available tape space, 38620 KB, but cannot incremental dump new disk] planner: FATAL cannot fit anything on tape, bailing out if i use runtapes = 2 it works. I can only write on DVD at once. Can I use tape_splitsize in this scenario or shuld i backup the 5 GB folder in 2 pieces? I hope you can help me Sebastian
