Hi, I make use of shadow_copy2 and root preexec. The vfs root preexec is responsible to auto create home directories which initially don't exist. The script behind it is well tested and works perfectly. Unfortunaltely shadow_copy2 seems to be called before root preexec and fails due to the missing ZFS home share which ca...

Hi, Can anyone reassure that files & folders made available to windows via vfs shadow_copy2 cannot be modified in any way? My NAS backups are stored on an iscsi target formatted with ext4 & I'm concerned that they could be tampered with by a virus such as Cryptolocker. Thanks

Hello, since oure shadow_copy2 is running now. I have another question: Is it possible to uses the shadow-copy on a linux-client? We mount the share via cifs from the Samba-fileserver.

We have: vfs objects = shadow_copy2 zfsacl (Actually, vfs objects = shadow_copy2 zfsacl fruit streams_xattr, but I wanted to point out the order of shadow_copy2 and zfsacl). To rule out shadow:format problems, I would create just one snapshot with a simple name and configure shadow:format accordingly. Also, is /public the mountpo...

Hello, I did setup shadow_copy2 with BTRFS snapshots. While this works fine for directories Windows does not show any previous versions for files. I couldn?t find anything regarding this, only one other using complaining about this in the OMV forums. Is this expected behaviour? Regards, Alexander

Hi there I'm having some troubles with Shadow Copy2 & zfs Snapshots. I have hourly and daily snapshots. If I use the following settings it works (but omits daily snapshots): vfs objects = shadow_copy2 shadow:snapdir = .zfs/snapshot shadow:sort = desc shadow:localtime = yes shadow:format = easysnap-hourly_%Y-%m-%d-%H-%M-UTC However when I try to use the BRE with the prefix, so that daily and hourly snapshots would be included, it won't work (no previous old versions being shown in...

Summary: what software are you using to generate (non-zfs) snapshots for use with vfs shadow_copy2? I've recently deployed a file server to a new site and one of my pet projects has been enabling Windows Previous Versions functionality. I had originally intended to use Snapper to generate and manage lvm thin snapshots, however it seems it's build scripts are broken on rhel8/centos8 s...

Hello, we are trying to configure a CTDB-Cluster with Glusterfs. We are using Samba 4.5 together with gluster 3.9. We set up a lvm2 thin-provisioned volume to use gluster-snapshots. Then we configured the first share without using shadow_copy2 and everything was working fine. Then we added the shadow_copy2 parameters, when we did a "smbclient" we got the following message: root at ng-data1:~# smbclient -m SMB3 //ctdb/gluster -k smb: \> ls NT_STATUS_NOT_FOUND listing \* On a windows-system we got the message "Element...
