SyncIQ - using the remote replica

Jeffrey Wiggins

Working with a customer recently with a large data store of 75TB of video data, the video data needs to be accessible in two different locations.

 

  • Location one is the primary location which ingests/add's content to the filesystem as well as performs a playout function for the environment.
  • Location two is a secondary site which needs a copy of the data for DR purposes but they would also like to read the data for local playout functions

 

The question around using SyncIQ to solve a replication, content distribution quandary that the customer is facing.

 

SyncIQ creates a secondary copy on the target cluster.  This copy is read only and normally not being used, however it is possible to create a read-only share on the secondary cluster pointing to the snapshot directory/pointer of the replica.

 

If the SyncIQ policy is creating multiple updates per day you can also automate the share definition via command line to point at the new share and the data becomes visible to the SMB share.

 

The destination filesystem will have a .snapshot_timestamp copy of the share.  Using a shell script you can check for the latest snapshot instance and redirect the share definition.  Testing this on a Windows SMB mount the windows file explorer updated the contents with the new read-only data.

 

Handy to use if you only need R/O data at the secondary site.
