如何用ufsrestore去备份 根目录，var，usr目录
以及cot3d0sx 上的目录（我的系统安置自c0t0d0s1上）

是不是搞错了，你到底是想BACKUP还是RESTORE啊？
ufsdump是 backup，有联机修改的应该unmount文件系统再做，那你应该知道怎么做了吧
#ufsdump 0uf /dev/rmt/0 /var ----(level 0 backup)
#ufsdump 0uf /dev/rmt/0 /dev/rdsk/c0t0d0s3
ufsrestore是 restore
恢复/ ,/var,/usr当然比较复杂，比如恢复/
#boot cdrom -s
#newfs /dev/rdsk/c0t0d0s0
#mount /dev/dsk/c0t0d0s0 /abc
#ufsrestore rf /dev/rmt/0
#cd /usr/platform/'uname -m'/lib/fs/ufs
#installboot bootblk /dev/rdsk/c0t0d0s0
#cd /
#unmount /abc
#init 6
呵呵！刚看过这部分内容，练习以下！

To restore the / (root) file system, boot from the Solaris CD-ROM and then run ufsrestore.
Note – If / (root), /usr, or the /var file system is unusable because of some type of corruption or damage, the system will not boot.
The following procedure demonstrates how to restore the / (root) file system on the boot disk c0t0d0s0.
1. Insert the Solaris 8 Software CD 1 of 2, and boot the CD-ROM with the single-user mode option.
ok boot cdrom -s
2. Create the new file system structure.
# newfs /dev/rdsk/c0t0d0s0
3. Mount the file system to an empty mount point directory, /a and change to that directory.
# mount /dev/dsk/c0t0d0s0 /a
# cd /a
4. Restore the / (root) file system from its backup tape.
# ufsrestore rf /dev/rmt/0
Note – Remember to always restore a file system starting with the level 0 backup tape and continuing with the next lowest level tape up through the highest level tape.
5. Remove the restoresymtable file.
# rm restoresymtable
6. Install the bootblk in sectors 1–15 of the boot disk. Change to the directory containing the bootblk, and run the installboot command.
