I tried using dump and restore, but it would take about 100+ disks to back things up. Instead I figured out a simplistic way that seems to work very good (although real clunky). first. tar zcvfp root.mace1.tar.Z ... ... .. .. (where root.mace1.tar.Z is the archive and the ... 's are all the directories you want in it) then. tar cfLMpv /dev/rfd0a 10240 root.mace1.tar.Z to restore (much easier) tar xfLMOv /dev/rfd0a 10240 | tar zxvfpv - By using this method I can now backup my system in 65 disks instead of 100+ The only catch is you have to have enough disk space to create you initial tar files. If you have limited space you can add the hastle of multiple tar files. It may be clunky, but it sure works better than dump. Also you can view each disk for integrety by replace 'xvf' with 'tvf' Scott Mace -- ********************************************************************* * Scott Mace internet: smace@nyx.cs.du.edu * * emace@tenet.edu * *********************************************************************
