[David Lowry_1]

Is there a general rule of thumb with regard to the maximum file size allowable under HP-UX 11iv2?

Hi,

JFS (VxFS) Supported Sizes
The following table lists the maximum file and file system sizes that the Journaled File System (JFS)
supports. JFS is also known as the VERITAS File System (VxFS).
Note: Although it may be possible to create files or file systems larger than these documented limits,
HP does not support such files and file systems, and the results of using them may be unpredictable.

Generally, long before maximum allowed file sizes come into play, more practical considerations come to the forefront. For example, how long will it take to restore huge files from backup? What is the maximum file size that my backup program will support? Would my restores be faster if I had to restore just 1 of 100 10GB files rather than having to restore my single 1TB file?

Thanks for the info.
