Since I don't do Windows, I'm not familiar with ghost, but I gather from Wikipedia that it's more a disk cloning tool (bare metal backup/restore) than a conventional backup program, although some people may well use it for backups too. Zfs has send and receive commands, which more or less correspond to ufsdump and ufsrestore for ufs, except that the names send and receive are perhaps more appropriate, since the zfs(1m) man page says: > The format of the stream is evolving. No backwards compatibility is > guaranteed. You may not be able to receive your streams on future > versions of ZFS." which means to me that it's not a really good choice for archiving or long-term backups, but it should be ok for transferring zfs filesystems between systems that are the same OS version (or at any rate, close enough that the format of the zfs send/receive datastream is compatible). There are of course also generic archiving utilities that can be used for backup/restore, like tar (or star), pax, cpio, and so on. But as far as I know, there's no bare metal backup/restore facility that comes with Solaris, although there are some commercial (and probably quite expensive) products that do that. But there's probably nothing at all that's quite equivalent to Norton Ghost. One can of course use "dd" to copy entire raw disk partitions, but that won't set up the partitions, nor will it work as expected unless all disk sizes are identical (for filesystems that don't have the OS on them), or if the OS is on there, all hardware is identical. Depending on just what "personal configuration" you mean, you may not necessarily need to back up the whole system anyway. Which is another way of saying that I'm not sure your post was specific enough about what you're doing to make it possible to suggest the best available (and preferably free) solution.
