restore backup

[a***@public.gmane.org]

Hello!

I have zfs snapshot dump 'mydump'

Is it possible to mount it in linux?

I created pool mypool:
fallocate -l 31G mypool
zpool create ....

oit-01 nchkz # zpool list
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
mypool 30.8G 594K 30.7G 0% 1.00x ONLINE -
zfs receive -vF -d testpool < file.backup


and after ~5 minutes I've got error:
receiving full stream of storage/pub/files-lvvrElKzeMSeaL6x6B+***@public.gmane.org into
mypool/pub/files-lvvrElKzeMSeaL6x6B+***@public.gmane.org
cannot receive new filesystem stream: invalid backup stream

zpool iostat give me info what alloc upper to ~15Gb and after error it is
resets



And I'm tring to just mount this file:

oit-01 nchkz # mount -t zfs mydump /mnt/111
filesystem 'mydump' cannot be mounted, unable to open the dataset


(Sorry for my bad English)

A "zfs send" stream is not a valid file system and thus cannot be
mounted directly. Also, the "zfs" file system type expects a dataset
name (as indicated by the error message), not a file.

Are you absolutely, totally, positively sure that the stream file has
not been corrupted?

Yes, file is corrupted :(

but it is have data, is it possible to restore files from this snapshot? I
tryed testdisk. no results..
foremost can restore file, but without names :(

I have a question about how can I backup a server with FreeBSD 10.0 with
ZFS as filesystem. I want to mention it that it has 2 HDD's and I can store
the backup only to the second HDD.

So, I have following:

#gpart status

Name Status Components

da0p1 OK da0
da0p2 OK da0
da0p3 OK da0

da1p1 OK da1
da1p2 OK da1
da1p3 OK da1

What I want is to backup & compress entire data from ( da0 )da0p1, da0p2,
da0p3 in directory /var from da1p3.

#df -h /

size Used Available Capacity Mounted on
38Gb 11Gb 27Gb 29% /

#df -h /home

size Used Available Capacity Mounted on
32Gb 4.7Gb 27Gb 15% /usr/home

#df -h /var
size Used Available Capacity Mounted on
28Gb 357Mb 27.Gb 1% /var


Gived the premises of my problem who and how can help me to backup the
first HDD on the second HDD in /var partiton/directory ?

This is a forum for ZFS on Linux. While there are some overlaps between
platforms this isn't a general forum for ZFS on all platforms. The link
posted above for the FreeBSD forum would be a good place to ask the
question (zfs send and receive is probably the answer you're looking for
but they'll know for sure). Also don't hijack threads because it's rude and
makes it more difficult for people to follow the discussion.
