Re: [zfs-discuss] is zpool export/import | faster than rsync or cp

2009-04-01 Thread Cindy . Swearingen
Hi Harry, I was on vacation so am late to this discussion. For this part of your question: The zpool export/import feature is a pool-level operation for moving the pool, disks, and data to another system. For moving data from one pool to another pool, you would want to use zfs send/recv, rsync
