Hi,
I seem to run into trouble when I try to backup my mysql database
servers and the dump takes longer then 2 hours. I dont have a lot of
large databases, but a couple with some large tables. This is the case
on every single backup attempt i've had. (For the job status/run
report please see the end of the email).
Seems that because mysqldump doesnt output anything while dumping
those tables, that it just times out. I wrote the mysql_backup.sh
wrapper script to mysqldump
Note that I do have:
Heartbeat Interval = 300 # 5 min
set in the director (both in director and storage directives), file
and storage daemons.
Is there something that I'm missing? Should I consider doing the dumps
on cron a 3-4 hours before beginning the backup with bacula? Are there
any other suggestions out there?
Thanks for the help!
Regards,
Renato
