Assessment of the iteration that has ended

The goal of the previous iteration was:

Finish the work to change the Obnam client to use async Rust for making backups. Once this works and is merged, make a new release.

This was not achieved. Lars blames life and work keeping him busy, and world news making him depressed.

Discussion

See previous meeting. Nothing important has changed.

Goals

Goal for 1.0 (not changed this iteration)

The goal for version 1.0 is for Obnam to be an utterly boring backup solution for Linux command line users. It should just work, be performant, secure, and well-documented.

It is not a goal for version 1.0 to have been ported to other operating systems, but if there are volunteers to do that, and to commit to supporting their port, ports will be welcome.

Other user interfaces is likely to happen only after 1.0.

The server component will support multiple clients in a way that doesn’t let them see each other’s data. It is not a goal for clients to be able to share data, even if the clients trust each other.

Goal for the next few iterations (not changed for this iteration)

The goal for next few iterations is to have Obnam be performant. This will include, at least, making the client use more concurrency so that it can use more CPU cores to compute checksums for de-duplication.

Goal for this iteration (not changed for this iteration)

Finish the work to change the Obnam client to use async Rust for making backups. Once this works and is merged, make a new release.

Commitments for this iteration

Lars intends to change the obnam backup command to use async (obnam#113). After this is done, the client should be entirely async.

  • obnam#56 -- SQLite databases for generations have no metadata about themselves (1h)
  • obnam#113 -- Client is not async (4h)
  • obnam#121 -- Release process needs review, update (1h)
    • should probably make at least a trial release
  • obnam#133 -- Test suite assumes location of binary (1h)

That's a total of about 7 hours, rough estimate, for Lars.
