I attended OpenSolaris Storage Summit last weekend. There are lot of efforts going on to make OpenSolaris into a feature rich storage operating system. Some of the projects that are relevant to backup are NDMP, Storage de-duplication, Virus scanning, Disk encryption and ZFS hybrid storage pools.
I talked about Amanda network backup and recovery and how well it fits with OpenSolaris and ZFS plans. Amanda can backup ZFS filesystems taking advantage of ZFS snapshots. ZFS snapshots provides the ability to backup open files in Open Solaris. Amanda 2.6.1alpha OpenSolaris packages that are available for download takes advantage of this feature. Amanda can also take advantage of ZFS send/recv functionality to do block level backups. Amanda provides users flexibility of backing up ZFS filesystems at file level as well as block level using ZFS send/recv feature.
ZFS storage is an excellent target for Amanda backups. ZFS’s ease of administration, robustness and scalability makes it an ideal target for disk based backups.
Joe Little of Stanford University has written a blog on how to backup ZFS filesytems using Amanda to Amazon S3.
BTW, ZRM of MySQL already supports Open Solaris and takes advantage of ZFS snapshots for backing up MySQL.
