Example--Performing a Full Backup of a Home Directory
The following example shows how to do a full backup of the /export/home/kryten home directory. The following ufsdump options are included:
0 specifies that this is a 0
level dump (or a full backup)
u specifies that the /etc/dumpdates file is updated with the date of this backup
c identifies a cartridge tape device
f /dev/rmt/0 identifies the tape device
/export/home/kryten is the directory being
backed up
# ufsdump 0ucf /dev/rmt/0 /export/home/kryten
DUMP: Date of this level 0 dump: Tue Oct 07 08:41:41 2003
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rdsk/c0t0d0s0 (starbug:/) to /dev/rmt/0.
DUMP: Mapping (Pass I) [regular files]
