TKLBAM - option to force warning (rather than error) on missing files #1412
Description
Currently TKLBAM will error if it encounters a situation where a file that it expects to be there is missing. Under the notion of "best practices" any volatile files should be limited to specific filesystem locations (e.g. a cache directory). Any directories such as this should explicitly be excluded from backups.
Generally this is the desired behaviour and assuming that system emails are working as they should (a system level SMTP relay is recommended to ensure that works reliably) then the user will be notified if and when any errors occur so immediate investigation and action can be taken..
However there are likely edge cases (perhaps a sub-optimal plugin for a particular web app that doesn't follow best practice?) so allowing the user the option of forcing TKLBAM to only show a warning (rather than throwing an error) when an expected file is missing would be a nice feature.
