if you are at liberty to be specific, although this is not strictly a “jena” issue, yours would be an interesting account. that is, how do you do this now? - which hardware with which os(s) with which file system(s) and what network connectivity? - which database(s) with which proxies with which applications on which of the hosts? - which datasets stored in which form(s)? - which application access patterns? - which form(s) of backup and/or replication with which temporal pattern(s)? - which administration processes to manage the above? what fails and how? best regards, from berlin,
