What will br send when backuping to S3

[leeraya]

Question

I have a table(kv size:34GB).When i use br to backup it locally. The sst file is about 4.4GB. I just want to know what will br send when the backup target is AWS S3 34GB or 4.4GB ？

BR would compress the SST files it generated during backing up the KV pairs. Also, BR write the same content to any External Storages(e.g. local, S3, etc..). So the final size would likely be 4.4GB.

BTW, BR has been moved to pingcap/tidb, you can file your issues at there with label component/br so the developers of BR would reply your issue faster. :)
