This has been something I've been working on for the last few days and I've not yet found an adequate solution. I've looked at tar, cpio and pax as potential tools for backing up a ZFS filesystem to tape, but each has limitations. As of today, Sun do not provide the ability to reliably backup a Solaris installation without resorting to third party tools. This is crazy! The beauty of ufsdump/ufsrestore is that because it's bundled with the operating system, I can perform bare metal recovery using a Solaris DVD and locally attached tape drive. It's simple and arguably essential for system administrators. From my perspective, Sun really need to create a zfsdump/zfsrestore set of commands that perform block level backups of a specified filesystem (or snapshot) and that preserves ACLs, atime, sparse files, handles multiple tapes (many of us still use and rely on tape!) etc. Does anyone know the process to formally request this (we have a support contract), or would I be wasting my time?
