Speed up rsync backups to S3 Object Storage
robi last edited by robi
Since rsync uses a lot of chatter to xfer small files one at a time, this is the most inefficient way to talk to an object store.
Instead if there was a configurable "chunk" size of say 100MB saved locally first, then transferred via rsync, you'd get speed and efficiency gains.
The S3 protocol is file based and not rsync based. We don't have a choice

@girish you're not understanding this..
we're not changing the protocol.
we're simply pivoting what we point rsync at.
not the app and all it's small files directly,
but some collection of them neatly arranged in larger chunks files which all happens locally in a temp dir, before it's shuttled off to S3 efficiently.
This should also save space on the multipart overhead issue, which seems like another feature to address.
@robi Ah ok, some sort of differential backup with "packing". I think duplicity does something like this (or maybe it's duplicati, i get confused between the two).
