up until now i've abstained from having backups for the encrypted directories and partitions on my machines. since my attachment to this data has grown as of late, i would like to know if there are any "gotchas" for backing up encrypted data. the concern i have is that if a lot of changes are made to the mounted encrypted partitions while dumping the underlying unencrypted paritions that it may corrupt the backup.
there are two situations of this sort that are relevant: (1) image file that i mount using vnconfig from the /home partition (openbsd) (2) cgd disk with several partitions that correspond to a single image partition (netbsd) my suspicion is that the right thing to do in both cases is to backup the underlying partitions (/home for openbsd and /dev/wd0e for netbsd) using dump. i run a modded version of todd fries' backup script where the backup host ssh-es to the machine in question and dumps the partitions. will i run into problems using an openbsd machine as the backup host for the netbsd machine since FFS != FFSv2? apologies for using netbsd, but i couldn't get postfix + svnd to work right :). cheers, jake
