Need advice on create zpool on USB drive & retrieve archive

Hi jlliagre,

I have finally being able to create a recursive snapshot of all the filesystems using the following recommended command:

Code:

# zfs list -r rpool
# zfs snapshot -r rpool@001
# zfs send -R -p rpool@001 > /mnt/hostname_rpool@001.snapshot1

Where /mnt is the USB drive that is in UFS filesystem format. hostname_rpool@001.snapshot1 has been copied to /export/home and I need to get the following guidance:

Code:

( i ) List table of content of this archive
      How to list the TOC of hostname_rpool@001.snapshot1?
( ii ) Create zpool called backups on the same USB drive
       zpool create backups c0t0d0s2 (USB)
       zpool create backups/usbdrive
       cannot mount 'backups/usbdrive': failed to create mountpoint
       filesystems successfully created, but not mounted
       
( iii ) Extract the content from this archive on to zpool backups
        cat hostname_rpool@001.snapshot1 | zfs recv -d backups/usbdrive

I am stuck in step ( ii ) and need confirmation on whether command in ( iii ) will work. Also like to confirm that compression has already been used
when creating the snapshot.
It's a very slow process and I can only do it with your valuable helps.
Thanks a lot,
George
