Hello,

Currently I use a proprietary solution for backing up my vmware VMs: arc 
serve UDP. Creating a backup job is split into several sub-tasks. 
Example for a simple backup:

- Choice of source;
- Type of backup to make (complete, incremental ...);
- Destination;

Then I can add other tasks:
- Choice of source;
- Type of backup to make (complete, incremental ...);
- Local destination;
- Replication on another datastore;
- ...

Each subtask can have an action time range.
---------
| - Choice of source;
 From 10pm to 5am | - Type of backup to make (complete, incremental ...);
| - Local destination;
---------
---------
 From 8 am to 3 pm | - Replication on another datastore;
---------

Then it's up to the engine to launch tasks at the right time.


The replication on another medium (local or datacenter) with the 
certainty of the consistency of this one seems to me necessary. In case 
of crash of the main site the recovery plan of activity to rely on the 
copy in datacenter for with the most recent data and not as is the case 
with a differentiation of a day because the latest backup Is not consitante.


Philippe.
