For binary or executable storage, we recommend you look into file hosting services such as DropBox, rsync, rsnapshot, rdiff-backup, and so forth. Still not sure what to do? Review this post on stackoverflow for more ideas.
For a BitBucket repo, you still have a soft limit to 1GB and an hard limit to 2GB.
