Copy store using rsync without freeze?

witness_content

 

Env: TS 7.4.1 with DD and oracle DB / Search  / OS- RH Linux. --version  2.6.32-358.23.2.el6.x86_64 #1 SMP Sat Sep 14 05:32:37 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

 

This is not a HA environment. So for the purpose of maintaining content on a standby(passive), can I copy over /store using rsync and run is incrementally every hour to be as near to prod as possible and without iwfreeze.

 

If yes, is it preferable to do a block copy instead of just plain rsync( file copy).  I usually would not do it, however would like to know what folks have to say?

 

I know that the copied (rsync'd) store when used on another server(with same set of users - ldap),  works. However I might not have done complete testing of the application to see if at all there is any issue like missing content etc., 

 

Thanks in advance for sharing your tips and best practices.

You are playing with fire.  

 

A snaphot, which is instananious, would be consistent.  However a copy, esp one that takes a while, will be inconsistent if there is a lot of activity.  Depending on how the copy is done (DB first) it is possible the issues will be recoverable (new versions of a file but not in the DB). But if the DB is copied last, then you have the DB thinking there are copies of a file and it cannot find them. That would be really bad. 

 

You may want to run iwfsck on the copies you make and see if this will be an issue.
