I use it for backing up a 12 GB mail > database without problems. "mysqldump --single-transaction" is backing up all tables in a single transaction, see the remark "MUTUALLY exclusive with lock tables", meaning that NO other client can modify the tables/ data at that time (which may take some time for big databases ). mysqlhotcopy is only working on MyISAM table formats yet and again locking the whole table. But as its a read lock other clients can still read the data. However, this perl script runs only local (must be run on the server). As for the question about the online backup facility, I believe what meant is that you can run an online backup from a tool like phpmyadmin, xoops, basically a normal webpage, etc. The difference of all these tools is a) how they accesss and lock the tables/data you want to backup b) the format of the output file (txt,sql format, binary etc. c) the supported features I hope this answers some of your questions. Let me know if you need more details. Best regards Nils Valentin Tokyo/Japan > > Regards, > > Chris > > P.S. Keep up the great work over there at Novell!
