I investigated EBS snapshot as an option, but there were two problems. 1) cost as i mentioned initially - for just AOSP source tree alone you are looking at > 250GB and at a cost of $0.05 per GB you are already at > $10/month and 2) EBS snapshots lazy load from S3 which gives TERRIBLE performance which means you end up with far far slower builds. AWS released a feature "EBS Fast Snapshot Restore" to workaround this issue, but it's extremely expensive.

Are you doing partial clone? https://source.android.com/setup/build/downloading https://source.android.com/setup/build/downloading Although, an answer at https://stackoverflow.com/questions/33053615/how-to-download-only-a-working-directory-of-the-aosp-source-code-without-the-ent https://stackoverflow.com/questions/33053615/how-to-download... from October 2020 says that even a partial clone is still 73 GB in size!? That’s insane! How the heck come it’s so big?

  That's likely the size of the entire checked out tree, which would include all of the files. I just ran the command here and my AOSP 11.0 checkout is 54GB, minus any git history, since I clone from a local mirror and use '--reference' to avoid having to copy objects. A lot of the size here is from the various prebuilts, AOSP build is quite self-contained (jdk, clang, etc) and barely uses anything from the host.
