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 advance, Dedhi

...he entire filesystem (/snapshot). I somewhat shudder at the thought of having to restore /export/home this way to retrieve but a single file/directory. Am I overlooking something here or are people indeed resorting to tools like tar and the likes again to overcome all this? In my opinion ufsdump / ufsrestore was a major advantage over tar and I really would consider it a major drawback if that would be the only way to backup data in such a way where it can be more easily restored.

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 what''s changed between fs at 0 and fs at 1. I''d probably use this functionality to produce a list of files to backup with cpio. I don''t want to make arc...

...rn on reporting of disk errors as they occur? Of course I ran into the problem of not being able to get past the file causing the error but I suspect that''s a bug that has been fixed? FWIW, the problem of dealing with disk errors has always been why I''ve preferred to use ufsdump/ufsrestore than other tools for backups. Darren

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. I''m guessing that I can format the external HDD as a pool called ''backup'' and "zfs send -R ... | zfs rece...

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. If I try to setup grub

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?

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 have the original working smb.conf, and binaries. Our file server's netbios name is sporadics.

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?

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

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.

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

Hi All, I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see the same LUNs as serverA? Or does it have to have preexisting,
