No, FRS copies the whole directory. It's fairly fast, but if there is a
modification on both servers at the same time, there will be issues.

If you're able to tell Windows FRS which specific files to copy, then
SnapshotDeletionPolicy (in 2.3) should work for this.
It basically protects a consistent snapshot of your index, ensuring
those files will not be deleted, while not blocking further updates to
the index.

I'm wondering if this is a problem that lucene users have already
tackled. I have four copies of the application using a lucene
index. They are located on two physical servers with two copies on
each server accessing two copies of the lucene index. I use Windows
FRS (File Replication Service) to replicate the index between the two
servers.
Things work well most of the time, but sometimes, I believe under
load, the index doesn't get a chance to propagate before another
write takes place and it gets corrupted.
What would you recommend I use to keep the index in sync between the
four copies of the app?
