The servers are Solaris 10 with the OS on UFS filesystems. (In zfs terms, the pool is old/mature). Solaris has been patched to a fairly current level. Copying data from the zfs filesystem to the local ufs filesystem enjoys the same throughput as the backup system. The test was simple. Create a test filesystem on the zfs pool. Restore production email data to it. Reboot the server. Backup the data (29 minutes for a 15.8 gig of data). Reboot the server. Copy data from zfs to ufs using a 'cp -pr ...' command, which also took 29 minutes. And if anyone is interested it only took 15 minutes to restore (write) the 15.8GB of data over the network. -- Ed _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
