just adding my 2 cents-
we've had to move away from plesk in some of our hosting efforts so we can have better HA.
we've had to build large clustered web systems, which is not ideal.
we lose the primary tools our customers have grown to love, and our staff understands: plesk.
we would love to see some solution around plesk being clustered.
if we had a this, it would allow us to shutdown a plesk node, and keep the services up- we would probably drop our complex beast in favor for it.
there are many options, and we've even done labs to see if we could trick plesk into being this way. We fault at IP failover, there's not an easy way to create a floating IP setup.
We have looked at software load balancer to address this- but to make the whole thing slick, and keep the plesk updates flowing we would need a vendor-supported solution- so we stopped in our efforts.
For future reference (if needed), we were looking at this: http://securityrouter.org/
the interface is easy enough for most plesk admins, or IT generalists to deploy and use.
Hopefully you guys will get this feature up and running one day!

@Odin: there are many people waiting for a feature like this. Can we expect it in a narrower future?
Kind Regards,

That would be a great feature ... for a better sleeping...

If Plesk has his own failover Sync - we will use plesk instead of other Hosting Solutions.

Please add this functionality

For the same reasons as already mentioned I am in need for the same sceduling functionality. Sergey please put this in your prio list.

Set Plesk compatible to load-balancing

Need automatic failover too!

Need failover scenario in Plesk !!

This would perhaps also be good in a load balancer situation.

A lot of this can be done with the command line tools, such as "migrate", I believe. (Haven't done this for real myself but I don't see why it wouldn't work.)

Yes, an automatic scheduler for migration Manager would be very handy. Right now I operate a fall back shadow VPS for my main VPS. It has the same content and same Plesk config, although the hardware specs are budget type. But it works fine, just a bit slower. In case of severe problems of my main VPS I can switch DNS for all sites on it, and within short time all sites run from my shadow VPS.

A month ago this scenario actually happened to me, when my VPS had problems, and totally crashed when I tried to fix them. I quickly switched DNS to the shadow VPS, and my clients never noticed a thing. Then I just rebuild the main VPS and at night I used Migration Manager to put all Plesk content from my shadow VPS back to the main one.

An automatic scheduler would be a great feature!

Yes, we have some thoughts in this regards, but frankly it is not our top priority yet.

@Odin: are there any plans in this direction?

Great Feature!!!!

as I understand, Plesk Automation supports distributed roles (i.e db server, web server etc.) but no synchronization between servers. What I am looking for is an automated sync that I can easily switch DNS entries to change to my backup system without loosing too much changes, emails...

this can be done using there virtual product and there storage engine

agree with this : working like a rsync for selectable part of the server to simplify, all this triggable in a cron job (yes, it can be done with a Rsync, but this can be great to simplify all).

An automation or scheduling Plesk Migration Manager jobs might do it for me.

It would be fine, if at least all Plesk content could be synced.

This could be great feature
