Re: backup strategies



hi osamu...

cool....that your script goes to cdr ...
( looks like a manually run backup script due to "yn" question

but its not a full nor incremental backup since its not backing
up "user defined" system config changes in /usr/local, /usr/lib  ??
	- good and bad idea... but yet another option to do backups

i think $cdtemp should be in /tmp or /usr/tmp so that the temporary backup
files /home/ftp/cdrimage/ROOT$date.tar.gz does not backup also into
/home/ftp/cdrimage/HOME$date.tar.gz  and a partial copy of itself too ??

have fun
