Smart data seeding applies to File Collaboration, File Replication, and File Synchronization jobs.
Occasionally, a new host or a host which has been removed from the session for a long time, needs to be introduced into an existing collaboration. Smart Data Seeding supports integrating new hosts into a collaboration seamlessly. Conventional seeding methods take a long time over typically slow WAN connections and require a cut-over with a final scan to get the data synchronized. With Smart Data Seeding's default settings, real-time events are processed from the Smart Data Seeding hosts while the initial one-way background scan ensures the target(s) have all the files in place.
Smart Data Seeding provides the ability to set one or more participants in a Smart Data Seeding mode. Smart Data Seeding hosts are considered the hosts from where files will be copied to all the other participants in the session. When a host is in Smart Data Seeding mode, it follows the rules of the job’s Smart Data Seeding Mode configuration (see below). Initial scans run in a one-way mode to avoid bringing back deleted files. It is not recommended to have active (Active-Active) users on the target hosts. Once the initial scan is completed, the Smart Data Seeding host(s) are set back to their default full collaboration mode with no user interaction or final scan.
To enable advanced settings in the Conflict Resolution window, add the following fc.ini option and restart Peer Management Center:
fc.scan.enable.preseeding.ui=true
From the Conflict Resolution window, select from one of the following Smart Data Seeding modes:
Mode |
Description |
|---|---|
PASSIVE (Default) |
Initial scan will be one-way only with any host in Smart Data Seeding mode: •Real-time activity on Smart Data Seeding host is disabled. •Real-time events on that host will be quarantined. •Renamed files will be restored. |
PASSIVE_WITH_RESTORE |
Initial scan will be one-way only with any host in Smart Data Seeding mode: •Real-time activity on Smart Data Seeding host is disabled. •Any activity on that host will be restored to its original state. |
ACTIVE_LIMITED |
Initial scan will be one-way only with any host in Smart Data Seeding mode: •Real-time activity on Smart Data Seeding host is enabled in a limited mode (real-time file adds are processed). •Unsynchronized file updates will be quarantined. •Unsynchronized file renamed will be restored. •Unsynchronized file deletes will be restored. |
ACTIVE_FULL |
Initial scan will be one-way only with any host in Smart Data Seeding mode except for updates (updates will be processed as Latest Modified wins): •Real-time activity on Smart Data Seeding host is enabled with latest modified file wins, regardless if latest file is on the Smart Data Seeding host. |
REACTIVATION |
Initial Scan will be one-way only with any host in Smart Data Seeding mode: •Real-time activity on Smart Data Seeding host is enabled with Quarantine (Added and Updated Files will be quarantined during the scan). •Unsynchronized file updates will be quarantined during real-time. •Unsynchronized file renames will be restored. •Unsynchronized deletes will be restored. |
The default setting is ACTIVE_LIMITED, which will initiate a one-way scan with any host in Smart Data Seeding mode. During the scan, new files will be deleted, newer files will be overwritten, and deleted files will be restored on the Target(s). During real-time activity, add events will be processed, but updates will be quarantined if the files are unsynchronized. Renames and deletes will be restored if the files are unsynchronized.
The ACTIVE_LIMITED setting is recommended in most cases in which a new host or a host which has been removed from the session for a long time needs to be introduced into an existing collaboration.
