Smarter item load ordering during ProduceRestoreCollections (#3294)
Optimize loading items for restore a little bit by first grouping items
by directory, loading the directory once, and then loading all items
from the loaded directory. This brings item loading on my local machine
(communicating with remote S3) down to ~1.5min/1k items

Future improvements could lazily load items as they're returned in the
Items() call of each collection but doing so would change the semantics
of ProduceRestoreCollections() (specifically item not found errors would
be returned during Items() instead of during
ProduceRestoreCollections())

The kopia data collection has also been updated to hold onto a
reference to the folder it corresponds to. This folder reference is
used to service Fetch() calls

Corso is the first open-source tool that aims to assist IT admins with the critical task of protecting their Microsoft 365 data. It provides a reliable, secure, and efficient data protection engine. Admins decide where to store the backup data and have the flexibility to perform backups of their desired service through an intuitive interface. As Corso evolves, it can become a great building block for more complex data protection workflows.

Corso is currently in Beta.

Corso supports M365 Exchange and OneDrive with SharePoint and Teams support in active development. Coverage for more services, possibly beyond M365, will expand based on the interest and needs of the community.
