[ris-int] New RIS rawdata backup schedule

Just for your information:

OPS took over the backup of rawdata from me. I passed all tapes to OPS. 

New backup schedule is:

OPS keep two copy of the data, one is at OPS safe place and the other one 
is at ABN-Amro safe. Rawdata is written into tapes at OPS safe place once 
in a week (Firday's). For ABN-Amro, I do not know the schedule yet.

OPS related doc is available at

http://iii.ripe.net/ops/docs/areas/services/backup/risbackup.html

OPS also will do zero level backup, but time schedule is not decided
yet.

I have updated RIS operational doc through the latest changes.
