Wow! Thanks for the replies. Looks like I'll use rsync instead.
Thanks James, it hadn't occurred to me that the filing systems might
have different time resolutions. And thanks for the suggestion of rsync
and reducing its time resolution. I didn't know rsync could do that.
Thanks Akkana, for the suggestion of rsync and the idea of restricting
it to size changes. Because I use these kinds of backups mostly for
writing it is unlikely that two files the same sizes are different. It
does happen, for instance if I find a number of letter reversals (teh
instead of the, adn instead of and) and where I've typed the wrong
letter (id instead of is), but on the whole, most changed files have
more extensive alterations as I'm an inveterate fiddler, so that would work.
A. Mani, thanks for the answer, but I'm not sure what you mean. Do you
mean that the drive is mounted as root but tests done as user? If so,
that doesn't apply to Puppy Linux. It is a single-user linux where the
user runs as root.
For those horrified at that as a security risk, Puppy has almost no
servers running (unless explicitly started), and has the option to run
internet applications as a low privilege user. There was a long
discussion about security on the Puppy forums and the conclusion was
reached that it is virtually impossible to break into, but that even if
someone did, what we care most about is our data which is exactly what
is at risk in any Linux. Puppy can be installed in just a few minutes
(unlike most OSes), or even be run from CD (which makes its OS totally
safe). The advantages in freeing up use of the machine by operating as
root outweigh, in my opinion, the (unconvincing) security concerns.
(Though if anybody has compelling evidence to the contrary, I'm open to it.)
If you don't have any failures then you're not trying hard enough.
