FRS is still used for SYSVOL replication, but optionally, DFS replication may be used instead of FRS replication for SYSVOL shares, [4] and the FRS stopped. On up-level Windows Server 2008 domain controllers, SYSVOL replication is performed using DFS replication, by default [5] although NTFRS replication is also supported. On Windows Server ...
DRBD is a distributed replicated storage system for the Linux platform. It mirrors block devices between multiple hosts, functioning transparently to applications on the host systems. This replication can involve any type of block device, such as hard drives, partitions, RAID setups, or logical volumes. [3]
Free and open-source software portal; Unison is a file synchronization tool for Windows and various Unix-like systems (including macOS and Linux). [3] It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.
In a disaster recovery context, mirroring data over long distance is referred to as storage replication. Depending on the technologies used, replication can be performed synchronously, asynchronously, semi-synchronously, or point-in-time. Replication is enabled via microcode on the disk array controller or via server software. It is typically a ...
Data replication and computation replication both require processes to handle incoming events. Processes for data replication are passive and operate only to maintain the stored data, reply to read requests and apply updates. Computation replication is usually performed to provide fault-tolerance, and take over an operation if one component fails.
Btrfs can initiate an online check of the entire file system by triggering a file system scrub job that is performed in the background. The scrub job scans the entire file system for integrity and automatically attempts to report and repair any bad blocks it finds along the way.

In computer science, state machine replication (SMR) or state machine approach is a general method for implementing a fault-tolerant service by replicating servers and coordinating client interactions with server replicas. The approach also provides a framework for understanding and designing replication management protocols.
