features across more datastores before pushing mysql too far ahead. Given the growth of the team over the last 6 months or so I definitely agree that more bench depth on datastores would be of benefit to the project and community.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:black">Is the goal to provide a developer with an API call for /recover {"at": "2014-03-04 00:00:00.00Z"}? Supporting a true point in time recovery like that is going
to be very difficult. In a former life I worked with a group of DBAs that managed a large Oracle deployment and dealt with point in time recovery quite a bit. In fact, the ability to recover to a particular transaction ID from the bin logs rather than just
a timestamp was critical to support any kind of fault tolerance with our replication setup (just a heads up that these things are likely going to be problems when we combine backup/restore with clustering/replication).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:black">Incremental backups and point in time recovery are great features that I would love to see a part of Trove. What I'm worried about is that we're pushing forward
on these features without enough datastore experts weighing in on what realistic expectations are for these features across data stores and how these features might impact replication/clustering. Don't get me wrong, Xtrabackup is a neat tool, but I don't want
to see us build an entire API spec around it.<o:p></o:p></span></p>

to see more backup operations implemented by the requested/merged data stores before we start talking about point in time recovery.<o:p></o:p></span></p>

<span style="font-size:11.5pt;font-family:"Arial","sans-serif";color:black">Every once in a while, an event might happen that corrupts a database. We have all made a stupid mistake at least once that had trashed a database. When this happens what do you do?
If you do not have a database backup, then you had better own up to the problem you caused and tell your boss that you screwed up. If you do have at least a complete database backup then you most likely will be able to recover the corrupted database, up to
the point that you corrupted the data. This article will discuss how to use a point in time restore to recover your databases.

<span style="font-size:11.5pt;font-family:"Arial","sans-serif";color:black">So what is a point in time recovery? A point in time recovery is restoring a database to a specified date and time. When you have completed a point in time recovery, your database will
be in the state it was at the specific date and time you identified when restoring your database. A point in time recovery is a method to recover your database to any point in time since the last database backup.</span><span style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:black"><o:p></o:p></span></p>

<span style="font-size:11.5pt;font-family:"Arial","sans-serif";color:black">In order to perform a point in time recovery you will need to have an entire series of backups (complete, differential, and transaction log backups) up to and/or beyond the point in
time in which you want to recover. If you are missing any backups, or have truncated the transaction log without first performing a transaction log backup, then you will not be able to perform a point in time recovery. At a minimum, you will need a complete
backup and all the transaction log backups taken following the complete backup. Optionally if you are taking differential backups, then you will need the complete backup, the last differential backup prior to the corruption, then all the transaction log backups
taken following the differential backup.</span><span style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:black"><o:p></o:p></span></p>
