Linux Journal recently had a way to copy disks:
tar clf - . | ( umask 0; cd /dir/to/copy/to; tar xvf - )
c = create
l = stay on local file system (don't cross
filesystem boundaries)
f = file (the next argument is the
name of the tarfile or "-")
- = write to standard out or
read from standard in
x = extract
v = verbose
"umask 0" ensures that the new files have the same permissions
as the old ones.
I tested it and it seemed to work great. What I am wondering is using this
with two identical drives on the same machine as a way to routinely back
up the first drive to the second. But in subsequent backups, how could I
employ the "find" command to just back up files that have changed since
the last backup?
