How do you convert Page Blob to RDB (redis dump)

I have a 26gb redis cache which automatically backs up to azure blob storage.
The files in the repo are split at 1.5gb intervals and stored in "page blob" format.
How do I go about converting those to the expected dump.rdb format so we can run testing external to the platform?

@cmk Thanks for raising this question! Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.

Blob is just the container for binary data – the format for whatever is uploaded there isn’t going to change.

Hope this helps!

Kindly let us know if the above helps or you need further assistance on this issue.

Hmm that doesn't really answer it.

We're using Azure Redis Cache; The service makes its backups to Blob Store but in doing so, stores the backup as multiple parts.
In comparison in AWS Elasticache the backups are made to (s3) blob store, but the backup format is the standard RDB file from Redis.

Azure's altering the format; how do you recreate the RDB from the Azure multi-part backup?
