[OpenIndiana-discuss] Backups and snapshots

[Gregory Youngblood]

What I've done is use CIFS server for Windows users, then use autosnapshot to take regularly scheduled snapshots. For windows users this has the advantage of the snapshots showing up under "Previous Versions" tab when right clicking on a file or folder. :) 

I've used iSCSI for VMs, but as I understand it the zfs snapshot of the iscsi volume would be a point in time image, as if the machine just stopped. Most of the time it's probably not going to be a problem, except when it is. :)

I also prefer NFS for exporting to Linux/Solaris/Unix. Can use to export to Mac as well, though AFP would allow the mac to use the share as a time machine; I dont think NFS does.
