How to make a backup copy of the database in the absence of space?

Question

Database

The mysql database weighs 90 GB, 100 are available on the hosting. It will most likely not shrink to 10, and the question is not about that. Are there any options in this case? Replication to another server only? By tables to copy? What if it's all in one table?

Answer 1

mysqldumpbladb | gzip | ssh remotehost "cat > /backup/dump.sql.gz"

Answer 2

mysqldump from another host where there is enough space.
