i'm following the guide but after finishing all the passages (without errors), i can't see any previous version of the file.
I have tried with OMV 1.19 and with the Testing 2.0.13 with no success.I have also tried with protected storage (user with password) and unprotected storage (guest allowed).
All the test are done in a virtual machine with 2 drives, 1 is the system drive e 1 is the storage drive.
Previous versions are generated with the snapshots. Open a doc, make changes, save it, run a snapshot, then a previous version of the file should appear.
Show me your samba extra options please.
Is per share, that's correct. Let me look at the vm and let you know
There is an inconsistency in the guide, the snapshot generation line is
btrfs subvolume snapshot –r /media/uuid/@Documents /media/uuid/@Documents/.snapshots/@GMT-`date +%Y.%m.%d-%H.%M.%S`
it should be like
btrfs subvolume snapshot –r /media/uuid/@Documents /media/uuid/@Documents/.snapshots/@GMT_`date +%Y.%m.%d-%H.%M.%S`
changed GMT- to GMT_ to match the extra options in samba
Already changed that in the guide, it should work now, if you rename your snapshots using the underscore
Now it's fully working.
Thanks a lot and i'm glad that you find the error
Should this still work with Windows 10?
I just tried a quick test and I am not seeing any previous versions. In the UI in Windows, it says previous versions come from File History or system restore points.
I created a subvolume, shared it, put a file in it, snapped it, changed it.
I did have the extra options in my smb.conf for the share, but I used a custom format, not the default, and I used the snapdir and basedir options with absolute paths to keep the snapshots outside of the subvolume.
This should work from the docs, as far as I can see...
How long before previous versions show up, is it instant?
Just realised, /media/data is a symlink to /media/<UUID> - maybe that is a problem? Has anyone experienced that? Will test it later if not.
I haven't test this in Windows10. The previous versions should display as soon as the subvolume files have changes from the live one.
Pick a file do some changes and execute the snapshot
is there a way to restrict the shadow copys only to certain file extentions?
Is this method also possible for user homes share? And if not, is there another way?
Each home folder would have to be a sub volume. To not interfere with Omv rewrite conf you need to place a mkconf script in samba.d/ to append to homes definition.
maybe I am missing something on the samba side not sure.
yep, Ive created a Filesystem (ZFS) for each user, enabled the home directorys and also tried to edit the "30homes" in the mkconf folder. After Ive added the lines, mentioned in your How-To, the users cant access their home folder.
EDIT: Sorry, Ive not added the lines from your How-To....
I used lines from here: https://forums.freebsd.org/threads/32282/
Oh... and it is working when I set it for each normal share, but not for the home shares.
Thanks a lot for this,
is this also possible for a union filesystem of btrfs?
I have 4 drives, 2 TB, 2 TB, 3 TB, 3 TB,
all are with btrfs formatted and added to a snapraid. (for the parity and data recovery if one drive is broken)
i like to have one great pool of 7 TB, and in this pool i like to have several shared folders for:
and i like for each of this share a snapshot possibility for samba...
is this possible? how should i configurate? i tried your guid for anpshots only with a pool of mkfs-btrfs /dev/sda /dev/sdb
but in omv3 it was not possible to add this for acl / shared folders.
I am using omv3, and backport kernel 220.127.116.11
I have no idea. But my first guess is it won't work executing btrfs snapshots from the union point. Retrieving the vfs in the union mount as share maybe. You can report back. I honestly don't have time to test this.
The problem is
i can't add via omv webinterace a shared folder which is on a disk created by mkfs.btrfs /dev/sda /dev/sdb /dev/sdc
I tried the last days a lot of btrfs, omv shared folders and snapshots,
and in no configuration it worked.
my linux knowledge also is very very bad.
maybe, it could work by manually add the device via the /etc/openmediavault/config.xml in the mnt section,
but I don't know how to add this here.
I have 1 TB + 1 TB + 2 TB + 2 TB
mkfs.btrfs -d single /dev/disk/by-id/ata-ST31000524AS_6VPGPJ9W /dev/disk/by-id/ata-TOSHIBA_DT01ACA100_56JUEJ1MS /dev/disk/by-id/ata-WDC_WD20EADS-22R6B0_WD-WCAVY5199117
Every drives are now in /dev/sdc 3,7T 17M 3,7T 1% /media/0c445189-73fb-4eb2-9d3f-d498224a0d25
1 TB + 1 TB + 2 TB
After: Going to the path in media and using btrfs subvolume create /media/0c445189-73fb-4eb2-9d3f-d498224a0d25/storagepool and btrfs subvolume create /media/0c445189-73fb-4eb2-9d3f-d498224a0d25/storagepool/.snapshots
Trying to test snapshots with btrfs: btrfs subvolume snapshot –r /media/0c445189-73fb-4eb2-9d3f-d498224a0d25/storagepool /media/0c445189-73fb-4eb2-9d3f-d498224a0d25/storagepool/.snapshots/@GMT_`date +%Y.%m.%d-%H.%M.%S`
btrfs subvolume list /media/0c445189-73fb-4eb2-9d3f-d498224a0d25 returns:
I don't know, what the problem is... maybe it does not work with a union drive, even if its done with mkfs.btrfs -single
maybe, I have a solutions now, for the snapshot working...
I've made a mkfs.btrfs -L MyStorage -d single /dev/sda /dev/sdc /dev/sdd
(sdb is my system, usb hdd, don't know why, but OMV did it as /dev/sdb)
So I have a /dev/sda 3,7T 17M 3,7T
Now, using OMV Webinterface for mounting it via Filesystem, and setting ACL, like in the guide...
Then via shell, navigating into:
Here I can create subvolumes, e.g.:
btrfs subvolume create Movies
btrfs subvolume create Movies/.snapshots
btrfs subvolume snapshot -r Movies/ Movies/.snapshots/@GMT_`date +%Y.%m.%d-%H.%M.%S`
(again, in the folder via ssh)
now I can set via OMV Webinterface Samba Shares on Movies, und with the guide, i see my volume shadow copies
btrfs subvolume list ./ (again via ssh in de /media/xxxxx/ folder)
