When your repo exceeds upload limit (GitHub 2GB), you can push in batches so you can store up to total size limit. (100GB) (Warning uses force push, ideally should be used for setting up new remote, once)

git-batch-push.sh

# Adjust the following variables as necessary
REMOTE=origin
BRANCH=$(git rev-parse --abbrev-ref HEAD)
BATCH_SIZE=250

# check if the branch exists on the remote
if git show-ref --quiet --verify refs/remotes/$REMOTE/$BRANCH; then
    # if so, only push the commits that are not on the remote already
    range=$REMOTE/$BRANCH..HEAD
else
    # else push all the commits
    range=HEAD
fi
# count the number of commits to push
n=$(git log --first-parent --format=format:x $range | wc -l)

# push each batch
for i in $(seq $n -$BATCH_SIZE 1); do
    # get the hash of the commit to push
    h=$(git log --first-parent --reverse --format=format:%H --skip $i -n1)
    echo "Pushing $h..."
    git push $REMOTE ${h}:refs/heads/$BRANCH --force
done
# push the final partial batch
git push $REMOTE HEAD:refs/heads/$BRANCH --force
