on the one hand this sounds like a good system because your backup is
bootable, but some problems come to mind. mostly with the theory, not the
method.
i'm assuming that you just keep one backup copy, so correct me if i am
wrong.
the problem with this is that if you backup errors or a program upgrade
that you later decided that you didn't want you can't get to the previous
backups because you just overwrote them with the new backup.
also, it is better to put backups on removable media so that it is
possible to move them offsite. and that doesn't mean that you are stuck
with tape drives either -- i use a Jaz drive.
i also organize my linux installation so that backups are small but
important stuff is always safeguarded. first, when i use a distribution
(i use Redhat at the moment but wish to switch to Debian once things
settle down a bit with the 1.2 release) i use it just to get the basic
system installed and up and running. basically i still have a stock
Redhat distribution on my drive. i then make good use of /usr/local/
(which is on a seperate partition) by downloading all `extra' software
that i don't feel serves as basic part of the unix system in .tgz format.
I then install them to the /usr/local/ filesystem making symlinks to
places elsewhere, but only if required (you can change a lot of default
behavior and installation locations at compile time if you just futz
around a bit).
(`basic' may be different for everyone but for me it includes: the base
system, XFree86, libraries, TeX/LaTeX, basic text editors, development
stuff, and anything related to the _basic_ operation of the system).
that way i can just backup /usr/local/, any configuration files
throughout the system, the mail and news spools, and the /home filesystem.
all the `basic' unix applications and tools can be reinstalled from a
distribution as the core system. then my /usr/local/, /home/, and /var/
filesystems can be restored from backups and mounted into the system.
hopefully this makes sense to someone. any comments would be greatly
appreciated.
