Personally I prefer simple and unobtrusive solutions, e.g. dump/restore with ufs/xfs, or send/receive with zfs, or even dd or tar. It depends on the type of applications you have running in a zone. For example, taking a zfs snapshot may not necessarily provide a consistent backup for SQL databases or other data sitting in application's buffers. I think the safest way is to shut down a zone, take a snapshot, start a zone and then perform backup of the snapshot in your own time. If you have a single appliance and take backup infrequently, then attaching a USB disk to store backups is simple and effective. However, if you have multiple appliances and want to run periodic backup scripts, then a dedicated backup appliance may scale better. There are free and commercial backup software/hardware which support multiple protocols (SMB, NFS, iSCSI, etc) and can be used with different OSes. The downside with such solutions is complexity and inevitable bugs in some of the software, which may result in corrupt or unrecoverable backups. ------------------------------------------ illumos: illumos-discuss Permalink: https://illumos.topicbox.com/groups/discuss/Tb9ca268d06c16ac1-M47c6ff8839e628f1dc359538 Delivery options: https://illumos.topicbox.com/groups/discuss/subscription
