[Borgbackup] borg info very long

You mean that a single file in your backup data source set (input files)
was rather big?

That just lists the manifest (all archive names/timestamps).

^ This means what it says. If you install borg from source, this often
means a missing C++ compiler.

The python version of msgpack is slower than the compiled C version of
msgpack.

That's strange. Not sure it could be caused by just the msgpack issue or
if there was something else going wrong. Are your disks ok?

borg check first does a repository (low level) check and then it checks
all archives in the repository (higher level).

Check what's up with your msgpack. Make sure you don't get that warning
by having a correctly compiled msgpack.

Our docs says what additional packages you need before (re-)installing
msgpack, so it gets compiled.
