Windows 7 UDF recommended (over ISO9960/Joliet) for data file backups on DVD/BR?

[pstein]

Occasionally I do some data file backups onto DVD and BlueRay medias.

My burning program offers some media file systems (even in combination):

ISO 9960 - Joliet - UDF

Which one should I use?

Is it correct that understanding the file system is a matter of the appropriate driver of the operating system and NOT a hardware matter of the DVD/BR burning device?

So all new DVD/BR burner offer UDF v2.60 burning as long as the OS offers the drivers.
Is this correct?

I heard UDF v2.60 ist the newest most advanced one.
As we use Windows 7 and Windows 7 CAN DO UDF we should prefer this?

Thx
Peter

When choosing a file system for burning data backups onto DVD and Blu-ray media, you have several options available, including ISO 9660, Joliet, and UDF (Universal Disk Format). Here's a breakdown of each file system and some recommendations:

1. ISO 9660:
   • ISO 9660 is a standard file system for optical media such as CDs, DVDs, and Blu-ray discs.
   • It has limitations on file name length and character types due to its age.
   • It is widely supported by many operating systems and can be read by various devices.
   []Joliet:
   • Joliet is an extension of the ISO 9660 file system developed by Microsoft to allow longer file names.
   • It enables the use of Unicode characters in file names, improving compatibility for Windows systems.
   []UDF (Universal Disk Format):
   • UDF is a modern file system designed for optical media, including DVDs and Blu-ray discs.
   • It provides support for larger file sizes, better metadata handling, and improved file system features.
   • UDF is recommended for newer discs and offers better compatibility with modern systems. In your case, considering that UDF is the most advanced file system for optical media and offers better support for larger file sizes and improved features, using UDF, specifically version 2.60, would be a good choice for data backups on DVD and Blu-ray media. Regarding your questions:
     • File System Support: The file system support is primarily a software matter related to the drivers and operating system capabilities rather than the hardware of the DVD/Blu-ray burning device.
     • UDF v2.60 Support: Most new DVD/Blu-ray burners should support UDF v2.60 burning, provided that the operating system offers the necessary drivers.
     • Windows 7 and UDF Support: Windows 7 does support UDF, and using UDF v2.60 would be suitable for compatibility with your operating system.
     Therefore, opting for UDF v2.60 for your data backups on DVD and Blu-ray media, especially with a Windows 7 system, is a good choice for better compatibility and modern file system features.
