File Conflict and Quarantine Scenarios

A job is started and Initial Scan Logic is performed on a file:

If the file has never been synchronized by Peer Management Center and if file sizes and last modified times do not match on all participating hosts, or if the file does not exist on one or more hosts, then the file will be synchronized based on the file conflict resolution strategy, which is typically the most recent last modified time.

Files that have previously been synchronized by Peer Management Center where just a single file’s last modified timestamp is newer than the last recorded timestamp, then that file will be synchronized to all other hosts.  However, if two or more files have a more recent last modified timestamp than was last recorded timestamp, then the file will be quarantined (this is the default behavior and can be disabled by deselecting the file conflict resolution strategy Quarantine Offline Version Conflicts option).

A single user has a file opened before starting a collaboration job:

A file conflict will be created with a status of Pending Initial Synchronization.  After the user closes the file, if all file sizes and timestamps match, then the file conflict is removed and no synchronization is performed.  However, if any file last modified times or file sizes do not match, the file will be synchronized or quarantined based on the file conflict resolution strategy and according to the initial scan logic detailed above.  Once the file is synchronized, the file conflict will be removed.

Two or more users have a file open before starting a collaboration job

A file conflict will be created with a status of Pending Conflict Resolution.  After the users close all files, the conflict will be removed if the last modified timestamp matches on all files.  Otherwise, if the file has never been synchronized by Peer Management Center, then the file conflict status will be updated to Quarantined.  However, if the file has previously been synchronized by Peer Management Center, then the file will be synchronized or quarantined based on the file conflict resolution strategy and according to the initial scan logic detailed above.

Two or more users open a file at the same time

In the rare situation when two users open a file at the same time, or in-and-around the same time and Peer Management Center is unable to obtain corresponding locks on target hosts before this happens (this is dependent on WAN latency and other factors), then a file conflict will be created with a status of Pending Conflict Resolution.  After all users close the files, file lock conflict resolution will be performed as follows:

oIf all files last modified timestamps and file sizes match, then the file conflict will be removed.

oIf only a single file has been modified, then the file that changed is synchronized or quarantined based on the configured file conflict resolution strategy and according to the initial scan logic detailed above.

oIf two or more files have been modified since it was opened, then the file conflict status will be updated to quarantined.
