tar -cf /dev/rmt/0 /

[tyagineeraj]

if we backup complete file system using
tar -cf /dev/rmt/0 /

how would we restor because tar -tv shows
directories like
//usr/..
//etc/..

etc.
while restoring would it put //usr ?? / cannot be created under /

any idia?

thanks

Neeraj,

That may work as it is. In my experience a double slash in a path eg. "cd /home//mlacey" is interpreted correctly as a single slash. Mike

i was having deja-vu then for a second (i'm sure i replied to this ...)

it'd be better for you though if you tar'd with respect to a directory rather than to it specifically, that way you can restore the files to a different place on your file system.

i.e. 'cd /;tar -cf /dev/rmt/0 .' would allow you to extract any of the files safely to any position.

on a linux system (with only one partition mounted) you could effectively recreate the file system by tar'ing the whole thing mounting a new disk as say '/mnt'; change directory to /mnt and then tar xf /dev/rmt/0 to extract everything back exactly the same.

makes giving files to people in tar/zip'ed format a lot more friendly.
