Absolutely.

Well, "data safety" setup is difficult for home use. However, as has
been pointed out before, usb-storage is cheap.

In comparison to what? In comparison to equivalent HD in a USB drive
caddy maybe. In comparison to 10/20Gb tape definitely. In comparison to
a DVD definitely not.

You can get the advantange of random RW which is damn difficult on most
media orientated DVD/CD devices and media. (DVD-RAM is possible if can
find the media and an appropriate device)

For example, I use
rsnapshot to do full backups, using symlinks. That's smart, because it
works automatically, and it in fact "only safes" differential data,
while still maintaining a "full backup anytime" structure that makes it
ease to revert to previous (backup-)versions. You can configure it to
backup yearly, monthly, daily, hourly, minutely..., whatever you need,
according to your needs.

This is a good serious professional tool, but unfortunately to get the
most out it you need to be a good serious professional.

The only solution I can see is the use of external media sets. While
commercial outfits can afford the hardware and personnel to make
differential systems work well with external media and more
sophisticated strategies, there is not really anything reliable and easy
to use for home users in this category.


Well, while this may be true, I would think that most home users will be
ok with an automated, regularly scheduled backup of different
hours/days,weeks/monthes/years... to external media.


Yep but with what?

I think Verity Stobs summarises the situation of machine deterioration
rather succinctly in the link below...

I am certain that someone can come up with equivalent metrics for linux:-)


In case that does not suffice, you might add a few more portable
usb-harddisks, that you store externally at a remote location away from
your computer.

As in many cases this would lead to a additional 40% -50% of home user
machine cost in backup storage so I doubt it is a goer. They spend the
same much in DVDs in the end but it not an up front financial jolt so
more likely to be born.



If that does not do the trick, imho your needs are ripe for a
professional backup solution that needs a professional budget, accordingly.


The difficulty is many of the current home solutions are dire. GHOST has
degenerated from being something very useful to both windows and linux
users to being a temperamental monster. Most others solutions require
some understanding of backup cycles, and systems management.
