Backup Files Bigger than 4Gb in FAT Filesystems

Sometimes we need to copy files to Fat filesystem that are larger than 4Gb, which this filesystem do not support, if I need to do that just for some period (as backup), I use the following:

$ rar a -m0 -v500M -R <rar-file-name> <original-file>

It won't compress the file (-m0 parameter) and will divide the file into smaller 500M file (-v500M parameter).

I already used it in a lot of situations where I really needed to free some space in a more decent filesystem (usually my XFS home or root partitions).

Peace!
