I am doing some work on validated restore scenarios using the new Veeam Cloud Tier that backed by an Object Storage Repository pointing at an Amazon S3 Bucket. So that I am not messing with the live data I wanted a way to copy and access the objects from another bucket or folder. There is no option at the moment to achieve this via the AWS Console, however it can be done via the AWS CLI.

First step was to ensure I had the AWS CLI installed on my MBP and it was at the latest version:

For the first part of the copy process, I cheated and created a new Bucket from the AWS Console that was based on the one I wanted to copy.

Next step is to make sure that the AWS CLI is configured with the correct AWS Access and Secret keys. Once done, the command to copy/sync buckets is a simple one.

Obviously the time to complete the operation will depend on the amount of Objects in the Bucket and whether its cross region or local. It took about 4 hours to copy across ~50GB of data from US-EAST-2 to US-WEST-2 going at about 4MB/s. By default the process is shown on the screen.

Once the first pass was complete I ran the same command again which will this time look for differences between the source and destination and only sync the differences. You can run the command below to view the Total Objects and Total Size of both buckets for comparison.

That is it! Pretty simple process. I’ll blog around the actual reason behind the Veeam Cloud Tier requirement and put this into action at a later date!
