Since backups are the current topic here, I'll ask an old question:
How do large sites (like > 1000 volumes) do backups?
We have > 10,000 volumes, and the last I tried, AFS backup wrote tape marks
between volumes. (If doesn't any more, somebody let me know, please.) That's
a lot of space taken up (isn't it about 2 M/tape mark = 20 Gbyte) before
considering the data.
Therefore, we currently vos dump each volume in turn to disk, and use AIX
backup to write the volumes to tape. This takes about 10 hours/4.5 Gbyte of
data we are dumping on an RS/6000 930.
So, what are you other big sites doing? Ideas, please.
