We're storing about 4 million files (4 TB or so) of miscellaneous files, mainly Word and PDF, in Azure BLOB storage. I'm looking to replicate this data in a different cloud for disaster recovery and peace of mind, and Amazon S3 seems as good a candidate as any.
Trouble is, I don't have a local server large enough to hold a local copy of these files. Ideally, I'd want to sync right from Azure Blob to S3. We're adding new files continually, so the sync would need to be frequent as well (multiple times per day).
I see lots of options for download from Azure to local => upload from local to S3, but very little for direct Azure => S3 sync. What are some good options here?
