I guess ditto blocks would be protection enough, since the data would be duplicated between both disks. Of course, backups are your friend. > What problem are you trying to solve ?

Read performance would double, and this is very nice, but my main motivation would be disk space: I have some hundred of gigabytes of data that I could easily recover from a backup, or that I wouldn't mind to lose if something catastrofic enough occurs. For example, divx movies or MP3's files. Since I do daily backups, selective ZFS "copies" could almost double my diskspace. I don't need to mirror my "/usr/local/" if I have daily backups. But I could protect the boot environment or my mail dataset using ditto blocks. Playing with ZFS "copies", I can use a single pool and modulate space/protection per dataset according to my needs and compromises. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ [EMAIL PROTECTED] http://www.argo.es/~jcea/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:[EMAIL PROTECTED] _/_/ _/_/ _/_/_/_/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQCVAwUBRwObzZlgi5GaxT1NAQJq7gP/V1g6KUPS8T9hnA3KDmKMbIeDKoqphRO5 POehmhnWsPlO8BPa+CxT/ZRUwbNYCte9kYYWeJzXNRpUyGtFvREBjtgK6swIQXUC n0D0gG0yI4aU1qzdX8X4bqomDaoL/Ho7YQu00j+P8mEfUdYzqY/odOVklZKq92U3 zfyDj7fgTVQ= =cDSg -----END PGP SIGNATURE----- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
