Hi,
I want to use disabling auto flush to backup ES data. I want to learn
whether manual refresh operations flush indices or not?

Refresh does not causes the transaction log to be affected. Internally in
Lucene it does write some index files, but they are not "officially" part
of the index (until a "flush" in elasticsearch, which results in a Lucene
commit).

So When I disabled auto flushing, I can backup all data directory. I have
another question. Assume this backup took too much time. How will this
effect ES memory usage? may it cause OOM exception or etc?

By disabling flush, a small amount of information will be stored in memory
per operation, so yes, you will eventually run into memory problems, but it
will take time.
