...y useful, if i gonna make it under DEB, but at the moment i'm really get stucked, i try to describe what's the point now; 1 - load shadow_copy mod in smb.conf vfs objects = shadow_copy 2 - install shadow copy client in WinXPProf 3 - write script to make snapshot to my LVM2 + XFS system SNAPNAME=`date+%Y.%m.%d_%H.%M.%S` lvcreate -v -L10M -s -n $SNAPNAME /dev/lvmgroup1/home xfs_freeze -u /home mkdir /home/@GMT-$SN...

...FreeBSD, it was really slick and windows users could right-click and see the previous versions. Anyway the idea is simple -- add an option "shadowcopylinks" to zfs, and when a snapshot is created (and snapdir==visible), then do a symlink(? -- maybe something lower) from the .zfs/snapshot/snapname to @GMT-$time (time format documented in the above link -- and it must be GMT). Of course the symlink/whatever would get removed when the snapshot is removed. If we had that and auto snapshotting like 2 at 30m, 2 at 12h, 7 at 1d, 4 at 1w (take a snapshot every 30 minutes and keep the last 2, etc)...

I don't know if this was present (maybe not?) when the script was written, but the script for taking a snapshot in the instructions for shadow_copy: that looks like this: ---- xfs_freeze -f /home/ lvcreate -L10M -s -n $SNAPNAME /dev/Home/lvol0 xfs_freeze -u /home/ mkdir /home/shadow_share/@GMT-$SNAPNAME mount /dev/Home/$SNAPNAME \ /home/shadow_share/@GMT-$SNAPNAME -onouuid,ro ---- Causes an, apparently, well-known system hang when you do the lvcreate. The workaround is to NOT use xfs_freeze. I don't know if...

Hi there, i am trying to understand something that bothering me for some time now. A running domain has two things that someone needs to take backup. So there is the disk and the state. Using snapshots as checkpoint someone can take the disk snapshot but i cant understand how to "transfer" the saved state from "backup ed" disk. Reading through Kashyap's and Eric's

Thanks for your answer, I am trying to make a snapshot of whole virtual machine (disk, CPU state, memory). But I need to make this snapshot in matter of seconds. I have already try to create snapshot of disk, which is not problem. I use qcow2 format, and create new disk image using original disk image as backing file. But still I am not able to assign state of vm with new disk. I have found

I''ve been saving up a few wishlist items for zfs. Time to share. 1. A verbose (-v) option to the zfs commandline. In particular zfs sometimes takes a while to return from zfs snapshot -r tank/volumes at foo in the case where there are a great many iscsi shared volumes underneath. A little progress feedback would go a long way. In general I feel the zfs tools lack sufficient feedback

...0.5. The overall operation takes as long as a migration to file, but the guest continues to operate throughout that phase. The actual guest downtime is a mere fraction of a second at the point where the disk snapshots are taken once the migration to file completed. virsh snapshot-create-as $dom $snapname --live --memspec /path/to/file will store the memory state into /path/to/file, and create an external disk snapshot of each disk (you may need to use the --diskspec option if you want to control the filenames of those disk snapshots). > > I have already try to create snapshot of disk, whi...

Initial concept of "failover" Ensures first of all, that that snapshot exists on both sides. (should it allow hand-created snapshots?) Then configures snapshot on non-mas...

Greetings, I am developing a platform for test and debug use. The typical scenario I want to realize is the following: I run a .qcow2 image via QEMU-KVM, the running OS is not relevant. I want to take several snapshots of both Disk and RAM status; same file, separate files doesn't matter. I just need a way to have consistent information about them (better with XML description) and the data

All, I have a service that takes new live KVM snapshots Si regularly, keeps a fixed number N (Si ,..,Si-N+1), and therefore needs to delete Si-N in this cycle. Until libvirt includes support for this capability that is said to be available in qemu, what is a safe workflow to delete old live KVM snapshots w/o losing data. Do I need to pause/shut down the VM? The development environment is

Hi matt, I have some problems about understanding zfs COW implemention. Suppose b and c are both children dir of a, if c changes, there will be new versions of both a and c, namely c'' and a''. a a'' b c c'' Because ''..'' in b points to a before this change, shall we modify b to let ''..'' point to a''? If yes,
