- Hi,
- I'm running NetBSD Amiga 1.1 on an A3000. Just recently I aquired a
- second hand Tape backup unit. I couldn't find much documentation on
- the topic in the man pages, so I'm asking here:
-
- What is the best way to backup the whole filesystem?
- I have 2.7G HD storage and the Tapesize is 525Mb, so I assume I need
- to use something that lets me archive to multiple volumes. I found tar
- does the job, but I have to be very careful because it core dumps when
- it comes across some files it can't read.
- eg. stuff in the /dev/fd/fd /kern and /proc directories. I don't know
- how it would behave if it found some other unreadable file, but I
- don't trust it much anymore since it just core dumped and exited on me
- close to the end of my backup. (I did use the --ignore-failed-read
- flag).
-
- In order to get it going I ended up with the following command:
- tar --totals --exclude /dev/fd/fd --exclude /proc --exclude
- /kern --exclude /ados --exclude /ados2 --ignore-failed-read -cvpsSMf
- /dev/rst0 /
-
- Hey! it actually worked.
- One problem is that I can neither compress nor verify a multi volume
- archive in tar.
-
- Anyway, what would I do If I wanted to use cpio, or dd?
