I've been meaning to ask/point this out for some time now. Has anyone actually tried *restoring* a dump of a *reasonably sized* pool? The reason I'm asking is that as far as I understand the man page, restore runs completely in user space, so it is faced with the same problem as cp/rsync/tar - the need to keep an inode-to-path-name mapping for correctly re-creating hardlinks. It is possible that restore can handle this problem, but I wouldn't take it for granted without testing. > It's just like dd, only faster and more space efficient.

The fact that restore runs in user space may or may not mean that you can restore to a different file system type.

You should be able to feed that directly to 'sfdisk' to recreate the partition table (which, of course, is most useful with an identical target disk).
