Move MySQL database to another server I need to move 20 Gb MySQL database from on Debian server to another. The problem is that there is no way to create its backup since there are almost no free HDD space on the source server. What would you suggest?
Percona XtraBackup can stream the backup over the network directly to the second server, and use no disk space on the source server.

See examples here:
