Subject: UPDATE 970418: patch to allow subdir dump(8)s
To: None <current-users@NetBSD.ORG>
From: Luke Mewburn <lukem@connect.com.au>
List: current-users
Date: 04/18/1997 16:47:16
Here's a patch to allow you to dump(8) a subset of files on a
filesystem.
I.e, if you have /home as a mountpoint, you could do
dump 0f $TAPE /home/user1 /home/user2 /home/user3/foo
to just backup the directories or files referenced.
The patch also adds support for printing status information upon
receipt of a SIGINFO signal (refer to "stty status").
Could interested people test these in various situations, and get back
to me? I'd like to put these in the source tree soon. Thanks.
