Amanda server is a dedicated machine with 7.5 TB disks (about 2300 USD assembly machine, gives me over 4 weeks or daily incremental backup, but the duration really depends on your usage). The more sensitive services I also backup using the protocol own duplication (master-slave database, DNS replication, etc.) With MySQL server replication, you can have the slave server running your actual database and ready to go in case the primary crashes. If the availability of the service is really critical, you must consider an high-availability solution, not only a backup. With that I have all the needed information to restore a faulty service. >> - SAIT solution and backula. I used to use tapes, I have changed for disks, it is much much faster and easier. And cheaper! In a 3U enclosure you can have 16 disks, for 32TB of storage. >> • I am not a 100% sure these solutions will allow me to restart rapidly >> from a crash, specially for Ubuntu servers. Depends on how you define rapidly... Backup and high availability have different/complementary roles: the first one assures that no data are lost, the second assures that the service will always be available. You know your needs :) Best regards, Olivier
