backup and restore of ZFS root disk using DVD driveand DAT tape drive
Dear all,
given a DVD drive and DAT Tape Drive, and using Solaris 10 U7 (5/09), 
how can we plan for a total backup of ZFS root disk and procedure to 
recover that?
Previously using UFS, we just need to use boot from Solaris OS DVD
media, also using ufsdump, ufsrestore and installboot.
Anybody can point me on how to achieve the same thing when the whole
system disk are busted?
Thanks in

Still looking for answers to this one?  Any example syntax, gotchas

zfs receive - list contents of incremental stream?
Apologies up front for failing to find related posts...
Am I overlooking a way to get ''zfs send -i fs at 0 fs at 1 | zfs receive -n -v ...'' to show the contents of the stream?  I''m looking for the equivalent of ufsdump 1f - fs ... |  ufsrestore tv - . I''m hoping that this might be a faster way than using ''find fs -newer ...'' to learn

Error reporting & backup with tar
In the process of tar''ing up files in an older ZFS partition
(23.6.2005), the tar command seized up.  Truss showed it hanging
in stat64(), so I went looking for symptoms.
In "zpool status -ve", I found "4" in the SUM column.
Being from the old school, I did "dmesg", expecting to see some
kernel error message about the disk but found nothing.

Hi all,
We are having some problems getting a solaris 9(sparc) file server 
running samba 2.2.2 to authenticate aginst a windows NT 4 PDC.  Let me 
say first that this was all working at one time, then we had some data 
corrumption on our NFS mounted /usr/local, and had to restore from tape. 
  Due to some issues with solaris ufsdump and ufsrestore, stuff was not 
quite put back properly.  We do

ZFS Boot Won''t work with a straight or mirror zfsroot
Using build 70, I followed the zfsboot instructions at http:// 
www.opensolaris.org/os/community/zfs/boot/zfsboot-manual/  to the  
letter.
I tried first with a mirror zfsroot, when I try to boot to zfsboot  
the screen is flooded with "init(1M) exited on fatal signal 9"
Than I tried with a simple zfs pool (not mirrored) and it just  
reboots right away.

Illegal filename characters
Does anyone have a solution for the problem of file and directory names
containing characters which are OK in DOS/Windows but illegal (or at least
unwise) in Unix?
I have Windows clients who have written directory names containing "$"
characters to Samba shares on a Solaris box. 
This is fine for the clients, but plays havoc with Solaris programs 
needing to access the files, eg. backups

Best practice for full stystem backup - equivelent of ufsdump/ufsrestore
I''m looking for a way to backup my entire system, the rpool zfs pool to an external HDD so that it can be recovered in full if the internal HDD fails. Previously with Solaris 10 using UFS I would use ufsdump and ufsrestore, which worked so well, I was very confident with it. Now ZFS doesn''t have an exact replacement of this so I need to find a best practice to replace it.

The equivalent of Ghosting the system
If I were to lose my main hard drive, I would like to have the 
opportunity to do the same as I can do using Windows: restore from my 
USB and have a working system.
If I were to rsync everything on the main drive (excluding the backup 
drive, of course and a few other directories) to my USB drive, could I 
restore using some CD based version of Linux e.g. Knoppix?

Archive-to-DVD
Hi folks,
Here's the situation.  I have a group of engineers who love to save
things to disk.  Now that the filer is getting full, they are
interested in archiving some of those things to DVD.
The tress containing the things they want to archive are specified
like so: 
/path/path/path/A/04??
/path/path/path/B/04??
/path/path/path/A/05??

Email Server Backup Strategy
Hello,
Was thinking it would be wise to backup my server, in case anything
"bad" ever happened, so that I could quickly get up to speed.
1. clone the whole drive -- which might be the best to ensure I keep the
whole system working.
2. But, what about, if I just wanted to backup my Email server
components? Postfix - which I think is just config files, and Dovecot -
I think there is a

Best practice preparing for disk restoring system
I'd agree with you John.  I'm trying to get away from Amanda's 
unpredictability and go back to using scripts to drive dump (for 
ext2/3/4) and xfsdump (for xfs).
Is there any easy way to tell rear to include xfsdump and dump 
capability?  If the commands are there then its trivial to restore data.
What I've done in the past is before the nightly backup write a small

zfs and backup applications
Hi,
  I was wondering if there have been any conversations with backup vendors like Veritas or EMC regarding better integration with ZFS.  While I understand they can use the "native" mode of reading files from the filesystem, it would be great if there were agents that had options like making a snapshot and storing a "zfs backup" datastream that could be used for zfs restore.

schily tools
Hey folks,
I'm reading up on gtar for tape archiving and it sounds kind of nasty and
not something I really want to rely on.
It looks like star from the schily tools is preferred.  I'm using Centos
(and RHEL) 5.7 which seems to have star but not sdd.
Which leads me to believe that the Schily tools are maybe a bit "rogue"
My basic requirement with what I'm doing is to use
