Michael Eischer 89d3ce852b repository: extract Load/StoreJSONUnpacked
A Load/Store method for each data type is much clearer. As a result the
repository no longer needs a method to load / store json.

Michael Eischer fbcbd5318c repository: extract LoadTree/SaveTree
The repository has no real idea what a Tree is. So these methods never
belonged there.

doc: Add note about using rclone for Google Drive
It wasn't clear that Google Cloud Storage and Google Drive are two different services and that one should use the rclone backend for the latter. This commit adds a note with this information.

Michael Eischer ce89018902 Fix data race in blob_saver
After the `BlobSaver` job is submitted, the buffer can be released and
reused by another `FileSaver` even before `BlobSaver.Save` returns. That
FileSaver will the change `buf.Data` leading to wrong backup statistics.

Found by `go test -race ./...`:

Adjust worker goroutines to number of backend connections

Michael Eischer 3af9c2cc58 Document automatic CPU/IO-concurrency 2022-07-03 12:19:26 +02:00
Michael Eischer 6f53ecc1ae adapt workers based on whether an operation is CPU or IO-bound
Use runtime.GOMAXPROCS(0) as worker count for CPU-bound tasks,
repo.Connections() for IO-bound task and a combination if a task can be
both. Streaming packs is treated as IO-bound as adding more worker
cannot provide a speedup.

Typical IO-bound tasks are download / uploading / deleting files.
Decoding / Encoding / Verifying are usually CPU-bound. Several tasks are
a combination of both, e.g. for combined download and decode functions.
In the latter case add both limits together. As the backends have their
own concurrency limits restic still won't download more than
repo.Connections() files in parallel, but the additional workers can
decode already downloaded data in parallel.

Michael Eischer 753e56ee29 repository: Limit to a single pending pack file
Use only a single not completed pack file to keep the number of open and
active pack files low. The main change here is to defer hashing the pack
file to the upload step. This prevents the pack assembly step to become
a bottleneck as the only task is now to write data to the temporary pack
file.

The tests are cleaned up to no longer reimplement packer manager
functions.

Michael Eischer fa25d6118e archiver: Reduce tree saver concurrency
Large amount of tree savers have no obvious benefit, however they can
increase the amount of (potentially large) trees kept in memory.

Michael Eischer bba1e81719 archiver: Limit blob saver count to GOMAXPROCS
Now with the asynchronous uploaders there's no more benefit from using
more blob savers than we have CPUs. Thus use just one blob saver for
each CPU we are allowed to use.

Michael Eischer 120ccc8754 repository: Rework blob saving to use an async pack uploader
Previously, SaveAndEncrypt would assemble blobs into packs and either
return immediately if the pack is not yet full or upload the pack file
otherwise. The upload will block the current goroutine until it
finishes.

Now, the upload is done using separate goroutines. This requires changes
to the error handling. As uploads are no longer tied to a SaveAndEncrypt
call, failed uploads are signaled using an errgroup.

To count the uploaded amount of data, the pack header overhead is no
longer returned by `packer.Finalize` but rather by
`packer.HeaderOverhead`. This helper method is necessary to continue
returning the pack header overhead directly to the responsible call to
`repository.SaveBlob`. Without the method this would not be possible,
as packs are finalized asynchronously.
