We use Isilon for large-scale (~1PB) genome sequencer disk storage. I have been pleasantly surprised how well it's worked. NDMP is a drawback, but a good chunk of that is just NDMP's limitations. We use TSM for our backups, and using native TSM gives us incremental-forever backups. Using NDMP would mean that we would have to regular full backups of hundreds of terabytes of data. Our solution is to have a pair of 10GbE-attached NFS clients for our Isilon system, and perform incremental backups over NFS. Due to the nature of our data, we have a bunch of similarly-sized directories that we can easily divide between two daily backup schedules, and assign one schedule per backup client. We've sized the backup clients such that either one could complete both schedules in under 24 hours. We've been using this backup methodology for about six months now without issues. - -- - -- - -- Skylar Thompson ([email protected]) - -- http://www.cs.earlham.edu/~skylar/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk338N0ACgkQsc4yyULgN4Y0LQCfbtnoEp6lqas7VU9OTOhfWJ2K RtkAnRpEpKAhCAXDipaYkGT5RnfivoOT =x1Bw -----END PGP SIGNATURE----- _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
