storage-preview for az storage azcopy blob download is missing --overwrite option

[ejschoen]

Which version of the AzCopy was used?

storage-preview 1.0.0b2

Which platform are you using? (ex: Windows, Mac, Linux)

Linux

What command did you run?

az storage azcopy blob download ...

What problem was encountered?

Both azcopy and az storage blob download-(batch) support an --overwrite false option to prevent existing files from being overwritten. This is not available through az storage azcopy blob download, which makes it difficult to migrate from these commands when overwrite=false behavior is required.

How can we reproduce the problem in the simplest way?

Have you found a mitigation/solution?

For now, don't use the storage-preview version of azcopy blob download. But for various reasons (recursive download AND connection string support), az storage azcopy blob download would be more convenient.
