Compile a JasperReport file

I'm using JasperReport to generate a PDF. Now I'm using the compiled .jasper, file but I want a backup in case of error to let Jasper recompile the original JRXML file. How can I do this? Is this a best practice?

This is my code:

InputStream reportC1 = ReportService.class.getResourceAsStream(JASPER_IN_PACKAGE);
bytes = JasperRunManager.runReportToPdf(reportC1, params, new JRBeanCollectionDataSource(records));
PdfReader doc = new PdfReader(bytes);

Where JASPER_IN_PACKAGE is a constant to .jasper file.

You can easily compile .jrxml files with

JasperCompileManager.compileReportToFile(sourceFile, targetFile);

where sourceFile is a File to your .jrxml, targetFile is the File to your to-be-created .jasper file.

And for the "Best Practice": I always deploy only the .jrxml files and compile them if the respective .jasper file is older that the .jrxml file. This allows me to easily edit the source files without having to compile them locally. And it is IMHO also best practice because one should never commit anything which can be reconstructed, especially not binary content.
