Is it possible to List Azure Blobs Where Last Modified Date > Some Date

Question

Is it possible to List all blobs on a container where Last Modified Date is greater than a specified date.

I have a container with millions of blobs and want to copy those blobs to a backup container, however don't want to loop through all blobs checking each for Last Modified Date.

Is it possible to List all blobs on a container where Last Modified Date is greater than a specified date.

As of today it is not possible to do so. Blob service does not provide querying capabilities. When you list the blobs, Blob service will return you a list sorted by blob's name.

Not now, but going forward if you need this capability you may want to organize blobs by dates by prefixing their names with year, month and date. Then you can ask blob service to return you blobs names of which start with a particular prefix. If you use Azure App Service, do take a look at how diagnostics data for an Azure App Service is stored in a blob container. It does prefixing by year, month and date.
