  - Introduction
    HCL VersionVault MultiSite adds a powerful capability to HCL VersionVault. With MultiSite, developers at different locations can use the same HCL VersionVault versioned object base (VOB). For HCL VersionVault, each location (site) has its own copy (replica) of the VOB. At any time, changes made in one replica can be sent in update packets to other replicas. You can manage replicas by using the command-line tools.
  - MultiSite operation
  - Implementation planning
    Before you install and use HCL VersionVaultHCL Compass MultiSite, you need to plan your implementation.
  - MultiSite command set
    This section summarizes the commands for HCL VersionVault MultiSite and HCL VersionVault that display HCL VersionVault MultiSite information. There are a series of MultiSite commands and API functions that display or modify MultiSite information.
  - Packet transportation methods and configuration
    The method you choose for transporting packets between replicas depends on connectivity. If your replicas do not have IP connectivity, you must use a file-based transport method. If your replicas have connectivity, you can use the store-and-forward facility.
  - Feature levels
    Feature levels allow different replica hosts in a VOB family to run different versions of HCL VersionVault. You can raise the feature level of either a single replica host or an entire VOB family.
  - Creating VOB replicas
    Before creating a replica, you must make decisions about branching, mastership, identities and permissions preservation, and method of packet delivery.
  - Replica synchronization
    Replica synchronization uses the same export-transport-import procedure that is used during replica creation.

  - Using MultiSite for VOB backup and interoperability
    You can use HCL VersionVault MultiSite to back up a VOB and to provide access to VOBs in a heterogeneous network.
    - Backing up VOBs with MultiSite
      You can use HCL VersionVault MultiSite to perform VOB backups.
      - Using a backup replica
        To back up a VOB consistently, the VersionVault administrator must lock the VOB. However, many administrators cannot find convenient times to lock the VOB so that the lock does not interfere with development work. One solution is to use MultiSite to create a replica of a VOB in the same local area network as the original.
      - Using replicas with incremental backup
        When you use a replica as an incremental backup of a VOB, you still back up the original VOB. You set up a replica of the original VOB in the same local area network, and schedule frequent unidirectional synchronizations. If you restore the original VOB from backup, the replica serves as an incremental backup by supplying changes made since the last backup.
      - Restoring a replica from backup
        If you lock your primary replica to back it up, you must restore it from the backup medium and perform the restorereplica procedure.
    - Using MultiSite for interoperability
      You can use multiple replicas in local area networks to provide native access to VOBs in a heterogeneous network.
  - Troubleshooting MultiSite operations
    When you encounter a situation where running an HCL VersionVault MultiSite command produces an unexpected result, or produces a warning or error message, the information in this section can assist you in troubleshooting the problem.

Backing up VOBs with MultiSite

You can use HCL VersionVault MultiSite to perform VOB backups.

There are two ways to use MultiSite as a backup strategy:

Using a replica as a backup to avoid locking a VOB
Using multiple replicas to provide incremental backups

Using multiple replicas in a local area network may help with reliability, availability, performance, and backup strategy. However, recovery issues limit how easily and rapidly clients may be switched from one replica to another. The details of the recovery process are described in Restoring and replacing VOB replicas.

Using MultiSite for backups means that the backup replica needs to remain online so that it can be updated frequently from the original. Almost twice as much disk space is required (you do not need exactly twice as much space, because derived objects are not replicated and the cleartext pool for the backup replica is smaller or nonexistent). Also, you need a MultiSite license and an HCL VersionVault license for each developer who accesses the replicated VOB.
