Comments for implementing file archive system
  • don't copy significant data volumes over NFS regularly
  • make sure no part of the file archiving makes any use of NFS, including software and scripts you need, current directories, files copied in or out, log files, etc. Everything must happen completely on local disk
  • Make sure every step of installation and operation is automated and completely documented so anyone can take over from you at any time. Make sure anyone who does so can simply trash the entire existing system and reinstall it from scratch with simple copy and past of instructions from a wiki page -- as much as possible of this process needs to be automated.
  • Obviously anything kept on local disks should be considered completely expendable. Never ever keep anything precious on the machine. In fact you should consider the entire machine completely expendable, and never rely on any single piece of hardware to be there.
