002 - Wie groß sollten Dateien für ISP sein?

In principle ISP allows arbitrary file sizes. In practice, a certain minimum size is recommended, at least for archiving (for backup, you have little influence on the file sizes). Ideally, the files should be larger than a few hundred kilobytes. Archiving a few hundred files smaller than 100 KB is also no problem. Only in the case of larger quantities of small files should these be packed beforehand in tar format or as a ZIP file.
