Four questions here on CFIs (hey, it's only four :-D ):

How does NetWorker deal with these situations? Seems like it should be able to handle it, but just asking.

1. Is there any problem with an index being backed up by group 1 (following completion of its save sets) while the index is also being updated by save sets from group 2?

This can frequently happen during group overlap wherein there are multiple NSR client resources for the same client, and CFIs get backed up to same tape that the data wrote to. This is assuming you don't instead have the 'no index save' option enabled and are using something like 'savegrp -O index_group' once a day.

2. Similar to question 1. What happens if two more groups overlap wherein they're running against the same client, so they're both updating the same index at the same time?

I assume all the entries in the index are segregated, and this type of situation is a normal or expected occurrence which the software is built to deal with?

3. What happens if a backup is running/adding entries to the index while 'nsrim' is pruning the same index?

4. What happens if an index is being backed up while 'nsrim' is running?


Thanks.

George
