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:
dump -0aun -f /backup/fullbackup /store
As expected, the result is a dump file called 'fullbackup'
Then I tested a restore, by restoring the fullbackup file from /backup
to /store. I did the following:
1) made /store pristine: newfs -U /dev/ad4s1e
2) mounted /dev/ad4s1e on /store
3) cd into /store
4) ran the 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?
Thanks in advance for your help
