Daily snapshots as replacement for incremental backups
Hello, I have a situation where a zfs file server holding lots of graphic files cannot be backed up daily with a full backup. My idea was initially to run a full backup on Sunday through the lto library on more dedicated tapes, then have an incremental backup run on daily tapes. Brainstorming on this, led me to the idea that I could actually stop thinking about incremental backups (that may always

Find the difference between two snapshots
Hi everyone, Is there an easy way to find out which files has changed between two snapshots? Currently I''m doing a # rsync -arvn <snapshot1> <snapshot2> and it creates a list. But rsync needs to go through the whole filesystem and compare files. It would be nice if zfs would have this option builtin. Regards, Nickus

''zfs recv'' is very slow
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, i have two systems, A (Solaris 10 update 5) and B (Solaris 10 update 6). i''m using ''zfs send -i'' to replicate changes on A to B. however, the ''zfs recv'' on B is running extremely slowly. if i run the zfs send on A and redirect output to a file, it sends at 2MB/sec. but when i use ''zfs send

ZFS replication send/receive errors out
My full backup script errorred out the last two times I ran it. I''ve got a full Bash trace of it, so I know exactly what was done. There are a moderate number of snapshots on the zp1 pool, and I''m intending to replicate the whole thing into the backup pool. After housekeeping, I take make a current snapshot on the data pool (zp1). Since this is a new full backup, I then

Possible to dedpulicate read-only snapshots for space-efficient backups
Hey list, I wonder if it is possible to deduplicate read-only snapshots. Background: I''m using an bash/rsync script[1] to backup my whole system on a nightly basis to an attached USB3 drive into a scratch area, then take a snapshot of this area. I''d like to have these snapshots immutable, so they should be read-only. Since rsync won''t discover moved files but

zfs send hangs
My zfs filesystem hangs when transferring large filesystems (>500GB) with a couple dozen snapshots between servers using zfs send/receive with netcat. The transfer hangs about halfway through and is unkillable, freezing all IO to the filesystem, requiring a hard reboot. I have attempted this three times and failed every time. On the destination server I use: nc -l -p 8023 | zfs receive -vd sas

zfs send speed
Howdy folks. I''ve a customer looking to use ZFS in a DR situation. They have a large data store where they will be taking snapshots every N minutes or so, sending the difference of the snapshot and previous snapshot with zfs send -i to a remote host, and in case of DR firing up the secondary. However, I''ve seen a few references to the speed of zfs send being, well, a bit

[zfs] portable zfs send streams (preview webrev)
We have finished a beta version of the feature. A webrev for it can be found here: http://cr.illumos.org/~webrev/sensille/fits-send/ It adds a command ''zfs fits-send''. The resulting streams can currently only be received on btrfs, but more receivers will follow. It would be great if anyone interested could give it some testing and/or review. If there are no objections,

About snapshots or versioned backups
This may be a bit poorly thought through but in this case I don''t really know enough to really think it through. My back ground is linux... there I used a tool called rsnapshot which used rsync and some hardlink magic to create versioned backups. But take very little space. By versioned I don''t mean as in version control but just copies of files as they change. It worked by

Snapshots silently eating user quota
All, I assume this issue is pretty old given the time ZFS has been around. I have tried searching the list but could not get understand the structure of how ZFS actually takes snapshot space into account.

Cannot destroy snapshots: dataset does not exist
Hello, I have a ZFS filesystem (zpool version 26 on Nexenta CP 3.01) which I''d like to rollback but it''s having an existential crisis.

time-sliderd doesn''t remove snapshots
In the last few days my performance has gone to hell. I''m running: # uname -a SunOS nissan 5.11 snv_150 i86pc i386 i86pc (I''ll upgrade as soon as the desktop hang bug is fixed.) The performance problems seem to be due to excessive I/O on the main disk/pool. The only things I''ve changed recently is that I''ve created and destroyed a snapshot, and I used

Shadow Copy2 & zfs Snapshots

zfs send and recordsize
Hi Everyone, I perform a snapshot and a zfs send on a filesystem with a recordsize of 16k, and redirect the output to a plain file. Later, I use cat sentfs | zfs receive otherpool/filesystem. In this case the new filesystem''s recordsize will be the default 128k again. The other filesystem attributes (for example atime) are reverted to defaults too. Okay, I can set these later,

core dumps eating space in snapshots
I have many core files stuck in snapshots eating up gigs of my disk space. Most of these are BE''s which I don''t really want to delete right now. Is there a way to get rid of them? I know snapshots are RO but can I do some magic with clones and reclaim my space? -- This message posted from opensolaris.org

any more efficient way to transfer snapshot between two hosts than ssh tunnel?
Assuming in a secure and trusted env, we want to get the maximum transfer speed without the overhead from ssh. Thanks. Fred -------------- next part -------------- An HTML attachment was scrubbed...

safe zfs-level snapshots with a UFS-on-ZVOL filesystem?
I had some trouble installing a zone on ZFS with S10u4 (bug in the postgres packages) that went away when I used a ZVOL-backed UFS filesystem for the zonepath. I thought I''d push on with the experiment (in the hope Live Upgrade would be able to upgrade such a zone). It''s a bit unwieldy, but everything worked reasonably well - performance isn''t much worse than straight
