[opencms-dev] proposing a parameterized scheduled job backup

[Marko Riedel]

Hi folks,

I have continued to tinker with my Java class for scheduled job backups. It is now fully parameterized. The resources that are to be backed up go into the parameters "resourceNNN" where NNN is a number. The path to and prefix of the zip file go into the parameter "pathAndPrefix."

I hope you find it useful in your own installation. Please send any feedback you may have.

Best regards,

Marko
