Previously kopia wrapper has been transparently injecting and stripping out a "serialization version" for all items persisted in kopia. The version thus far has been hard-coded to `1` and has been stored in big endian format in the first 4 bytes of every kopia file This PR is a step towards getting serialization versions on a per-service/per-item basis. It exposes serialization readers that inject and strip out info to other packages This PR also slightly changes the serialization version format. The changes are two-fold: * the MSB is now used to represent if the item was deleted between the time it was discovered and when its data was requested * the serialization version number is set to uint16. This has no impact on existing persisted data since all versions are currently `1` (don't use more than 16-bits). This size can be expanded in the future if needed, but is mostly to enforce the idea that higher order bits shouldn't be used for version numbers right now --- #### Does this PR need a docs update or release note? - [ ] ✅ Yes, it's included - [ ] 🕐 Yes, but in a later PR - [x] ⛔ No #### Type of change - [x] 🌻 Feature - [ ] 🐛 Bugfix - [ ] 🗺️ Documentation - [ ] 🤖 Supportability/Tests - [ ] 💻 CI/Deployment - [ ] 🧹 Tech Debt/Cleanup #### Issue(s) * #4328 #### Test Plan - [ ] 💪 Manual - [x] ⚡ Unit test - [ ] 💚 E2E
Corso
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.
