Replicating a VOB between Windows and another platform

When setting up replicas on Windows® and other platforms (specifically Linux® and the UNIX® system) at different sites, there are configuration issues that must be addressed.

Note: If you plan to use MultiSite at a single site for interoperability between these different platforms, see Using MultiSite for VOB backup and interoperability. This information is not intended to address that issue, but to describe issues involved in setting up replicas on Windows and other platforms (specifically Linux and the UNIX system) at different sites.

If your sites do not have an IP connection, you must use electronic mail, CDs, tapes, or diskettes to transfer packets. You may have to solve compatibility problems if you choose to use tapes or diskettes. With electronic mail, you can use compatible encoding and compression methods. However, differences between VOBs on Windows and on the other platforms are handled automatically during packet import.

The most important problems you must prevent are file names that differ only in how they are capitalized and differences in use of line terminators. If file names that are case-sensitive are used at one replica and file names are not case-sensitive are used at another replica, errors can occur during synchronization. Differences in use of line terminators by text editors on various platforms can cause unexpected behavior during file comparisons and merges. Even if the contents of the files are identical, different line terminators indicate differences in the files and require a merge.
