Recommended approach to keep a HUGE domain in sync in two Plesk 11.5 servers

[PedroC]

Dear all,

We need to have a huge Plesk domain (several hundreds of GBs in mailboxes) in "soft" sync between two different servers that are in different locations. These two phys servers have identical hardware, identical OS and are licensed with the same Plesk version. Virtuozzo, shared storage or clustering are not an option here.

Syncing mailbox data is fine with rsync, the same with website files (no databases). This can be scheduled to run everyday, so after the intial sync this should be ok, no problems with the net. Re domain configuration (to sync mailboxes names, passwords, redirects, etc.) I tried Plesk backup to only backup "configuration", but looks like the restore needs to be done on the same physical server...

Any suggestions to approach this?

Regards

You can try to send the same API-RPC XML requests simultaneously to servers for domain reconfigurations.

Thanks for the reply Igor

Not very familiar with the API, do you mean "listening" for changes somehow in the active server (like when a user changes a password) and then sending the same change to the sync server via API call? What about the initial configuration sync?

Also, is there an easy way to tweak the Plesk backup file in order to be able to restore it in a different server?

Kind regards

You just create XML file with needed API-RPC request according to documentation http://download1.parallels.com/Plesk/PP11/11.5/Doc/en-US/online/plesk-api-rpc/ and send it by php or perl script on your Plesk servers. All described in XML file changes will be applied simultaneously.

PedroC, I haven't done this yet so please take this with a grain of salt, but I'd expect all the needed settings to be stored in the psa database, so probably dumping the latest copy on the backup server will help quite a bit. Also make sure you preserve the ownership and permissions when syncing the files across.
