The BSDs all use variants of UFS, and dump/restore understand UFS1 2.
The EXT2FS in use on Linux is a different animal altogether. I'm
surprised that it ever worked.

I am not sure what the heresy is here, but
dump/restore can be sensitive to OS and OS version.
There are many that it cannot cross, but some it can.
The main thing is to check it before depending on it.
I should add for clarity.

actually second was a guess. first was natural, as amd64 and i386 are both
little endian, intlong are same sized under gcc, and memory pointers are
not stored in dump files.

I did and it does.
you may try to compile OpenBSD restore from sources under FreeBSD and use
it.
compared to dump, restore does not do anything filesystem specific, just
reads input and make files.
if any - there should not be many fixes needed to make it compile
permissions are
back. This kind of weird since the OS drive hasn't changed. So, there
are the same users setup on the system. Any thoughts?
Well, dump/restore should result in permissions and flags and
everything being as before the dump. I have done the equivalent
many many times and not seen any
1) made /store pristine: newfs -U /dev/ad4s1e

Hi,
I have a box with three hard drives:
/dev/da0 - dedicated to the OS
/dev/ad4s1e - data drive - mounted as /store
/dev/ad5s1e - hold a backup of /dev/ad4 - mounted as /backup
I used 'dump' to backup everything from /store to /backup with the
following command:
: restore -r -uv -f /backup/fullbackup
5) remove 'restoresymtable' from /store
The restore went fine and I had all the files back. However, all file
permissions were gone. How can I preserve file permissions with dump /
restore?

Or after a restore, Windows would be able to read the files? What about dd
