show the up-to-date content

say i have two windows server, located in two site with distance. i have a folder in site A with many big image files. i want to sync the folder to site B and make it viewable in site B.
it seems replistor can do these. but i have two questions:
1) if i modify the file in site A, will people in site B see the changes (although i know some latency will be exist since Async replication)
why i ask this question is if i use mirrorview to replicate data, the target is hide from the host without promotion. only by make a snapshot, target host can see the data.any new changes will not reflect in the snapshot.
2) does replistor support two-way replication?

Yes there is a memory cache that is reserved for this (by default 10% of the system physical memory). Once this cache fills up it starts writing the cached data to the data directory on the disk. Once the connection is restored these cached changes are applied to the target system.

Hello,

Yes, the files on the target are accessible for Replistor replication. Usually you want to configure the replication so they are read only.
It is possible to configure two way replication of the same volume, but there are some limitations the most important one being that if the same files is edited on both sides at the same time the data will most likely get corrupted, so this is something to be avoided.

thanks for reply.
what if the replication channel is broken for some time? is there any temp space reserved at source host?
