#4975 Webmin variable substitution doesn't work with cron jobs

[Frank.R]

The webmin variable substitution doesn't work in automatic cron based backups in the MySQL modul.
If created an per database backup. The backup file looks like "$DB_%Y%m%d_%H%M.sql.gz".
If I start the backup from within webmin the result is like expected - $DB is replaced with the database name. But if the cron jobs start automatically, the result is like $DB_201706190000.sql.gz. $DB is not replaced with the database name.

I'm actually surprised that using $DB works anywhere, since there is no support for expanding it in the Webmin code!

[Jamie Cameron]

Do you have webmin_subs=1 set in your /etc/webmin/mysql/config file?

[Frank.R]

OK you are right, it also doesn't work in the webmin gui.
Yes, webmin_subs=1 is set in config.
I think I misunderstood webmin_subs.
It seems to be not possible to use webmin_subs to get the file name for the backup of the current database.

[Jamie Cameron]

That's correct - webmin_subs is only for including the hostname and a few other variables in the backup path.
