Interactive mode (-i)
For example, if you accidentally delete a file, say /etc/make.conf, you can use restore(8) in interactive mode to restore it:
# cd / # zcat /share/backup/coffin.lan/root.dump.gz | restore -ivf - Verify tape and initialize maps Header with wrong dumpdate. Dump date: Sat Oct 11 09:36:15 2008 Dumped from: the epoch Level 0 dump of / on coffin.lan:/dev/ad1s1a Label: none Extract directories from tape Initialize symbol table. restore > cd /etc restore > add make.conf warning: ./etc: File exists restore > extract Extract requested files extract file ./etc/make.conf Add links Set directory mode, owner, and times. set owner/mode for '.'? [yn] n restore > quit
Restore prints some warnings about "wrong dumpdate" but works as expected...
To do the same via network replace "zcat" with:
# ssh [email protected] zcat
Restore mode (-r)
The target file system should be made pristine with newfs(8), mounted and the user cd(1)'d into the pristine file system before starting the restoration of the initial level 0 backup.
If the new filesystems are mounted under /mnt, /mnt/var, /mnt/usr, /mnt/usr/home:
# cd /mnt # zcat /share/backup/coffin.lan/root.dump.gz | restore -rvf - # rm restoresymtable # cd /mnt/var # zcat /share/backup/coffin.lan/var.dump.gz | restore -rvf - # rm restoresymtable # cd /mnt/usr # zcat /share/backup/coffin.lan/usr.dump.gz | restore -rvf - # rm restoresymtable # cd /mnt/usr/home # zcat /share/backup/coffin.lan/home.dump.gz | restore -rvf - # rm restoresymtable
