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

Unreliable ZFS backups or....
I looked into backing up ZFS and quite honostly I can''t say I am convinced about its usefullness here when compared to the traditional ufsdump/restore. While snapshots are nice they can never substitute offline backups. And although you can keep quite some snapshots lying about it will consume diskspace, one of the reasons why people also keep offline backups.
However, while you can make

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.

security=domain problems
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

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

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.

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.

[LLVMdev] how to track down a kernel miscompilation?
For people who want to try hacking on the linux kernel with llvm, here
is a head start:
http://llvm.org/~alenhar2/k.tbz
This is a 2.6.27.5 kernel with a .config file for qemu/kvm with virtio
devices (I also think it will work with the default devices). The
build process uses llvm-gcc -> opt -> llc so you can add your own
(per-file) passes to the build process or debug specific passes.

[LLVMdev] how to track down a kernel miscompilation?
One other note I forgot...
sig_sysreturn (arch/x86/kernel/signal_32.c) has a magic fudge factor
to fix up stack layout differences between llvm and gcc. If when you
hit userspace you get signal handling errors, look at the frame
addresses printed out and adjust the fudge factor to make the frame
addresses match. (the code automatically enables the debug output
after the first signal frame

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?

Preferred backup s/w
Hi all,
What is the current preferred method for backing up ZFS data pools,
preferably using free ($0.00) software, and assuming that access to
individual files (a la ufsbackup/ufsrestore) is required?
TIA,

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

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
