In the process of recovery is quite simple and fast and the data needed can be accessible during the hour. For security reason the acces to this server is limited to the System Administrators, but a simple request is enough to obtaining the files needed. The cons is that the procedure of saving the complete Filer require a lot of time (around 3,5 Hours, today) and disk space (around 2.5 TByte now). For this reason we can guarantee access to only 30 days of backup. The presence of this backup is explained by the necessity to have a complete, simpler and and fast way to restore the content of Filer in case of complete crash of the system.
