[01] HOW OFTEN DO YOU BACKUP YOUR SERVERS? Back ups are done incrementally at a minimum of a weekly basis for MetaARPA members. The majority of files on the file servers get backed up at that time provided there is space. The priority is SDF specific files, then MetaARPA, ARPA and finally USERS. The only files that are not backed up are the ones in /tmp across all clients and servers. If you use /tmp for storage it should only be considered as short term storage. For instance, if a client machine has to be replaced due to hardware failure, you are not guaranteed that files in /tmp will appear on the replacement host. The back up disk array is only brought online during the weekly backup session. It is not accessible to members. File restores can be requested by posting a message on the bboard <REQUESTS> and specifying the full path location to the files or directory. You will receive an email with the location of your restored files. Its recommended to use the SDF 'delete, undelete and expunge' utilities which you can alias rm to in your .profile.
