Real time file replication open source

DFS latency about 60 minutes GPFS have different replication methods. In LAN Synchronous mirroring is real-time. Do you ever install GPFS for mirroring? Is this an error with 60 minutes latency?

DFS is nearly real time, depending on rate of changes to be replicated, available bandwidth and network latency. I have no idea where this 60 minutes latency idea comes from, but its is plain wrong.

DFS does not delay 60 minutes if the system is well set up and capacity is enough to replicate. I see replication in seconds. It's not. We're seeing sync issues multiple times a month which is intolerable for our scenario. Published: Written by Miller.

This is not the case with most replication solutions particularly with replication at the database level. Manual operations are required for resynchronizing a failed server. The application may even be stopped on the only remaining server during the resynchonization of the failed server.

The replication is working for databases but also for any files which shall be replicated. This not the case for replication at the database level. The replication is based on file directories that can be located anywhere even in the system disk. This is not the case with disk replication where special application configuration must be made to put the application data in a special disk.

The servers can be put in two remote sites. This is not the case with shared disk solutions. All SafeKit clustering features are working for 2 servers in remote sites.

If both servers are connected to the same IP network through an extended LAN between two remote sites, the virtual IP address of SafeKit is working with rerouting at level 2. If both servers are connected to two different IP networks between two remote sites, the virtual IP address can be configured at the level of a load balancer with the "healh check" of SafeKit. The solution works with only 2 servers and for the quorum network isolation between both sites , a simple split brain checker to a router is offered to support a single execution of the critical application.

This is not the case for most clustering solutions where a 3 rd server is required for the quorum. The secondary server is not dedicated to the restart of the primary server.

The cluster can be active-active by running 2 different mirror modules. This is not the case with a fault-tolerant system where the secondary is dedicated to the execution of the same application synchronized at the instruction level.

SafeKit implements a mirror cluster with replication and failover. But it imlements also a farm cluster with load balancing and failover. Thus a N-tiers architecture can be made highly available and load balanced with the same solution on Windows and Linux same installation, configuration, administration with the SafeKit console or with the command line interface. This is unique on the market. This is not the case with an architecture mixing different technologies for load balancing, replication and failover.

Quick application restart is not ensured with full virtual machines replication. The solution does not require load balancers or dedicated proxy servers above the farm for imlementing load balancing. SafeKit is installed directly on the application servers in the farm.

This is not the case with dedicated proxies on Linux. This is not the case with a specific multicast Ethernet address on Windows. This is not the case with other load balancing solutions.

They are able to make load balancing but they do not include a full clustering solution with restart scripts and automatic application restart in case of failure. They do not offer a replication option. But you found there are many places you need to change. Once your changed data on the source files, you need to duplicate again to keep the new data safe.

It seems very annoyed. A continuous data protection is necessary. Its File Sync feature allows you to make a real-time file replication to another local hard drive, external hard drive, network, even on two different computers, etc.
