Backup to Disk Folder and .bak file size Best Practices

If I am using backup to disk folders, what are the pro and cons of the following?

Pre-allocating media vs. no preallocation?
and: (what if I go over the preallocated amount)

Writing to large backup files vs. using the default 1GB files?

I look forward to understanding the best way to do proceed. (and being more informed :) )

Hi,

The option " Disk space" reserve to prevent a job from being written to
the backup-to-disk folder when the threshold that you specify is
reached.

Enter an amount of disk space to reserve on the disk. When this
threshold is reached, Backup Exec cannot submit jobs for
processing that are targeted to this backup-to-disk folder, but jobs
that are running will finish. The backup-to-disk status displays
Low Disk Space.

You must free some disk space to allow job submission to resume.

Hope this helps you,

Thanks,

Well,

I"m really looking to understand better what Veritas/Symantec was thinking as the most optimal way to use disk space with Backup to disk folders, and looking for some direction regarding how to best use them.

For example, by default, each backup file is one GB, which can make for hundreds of backup files, to me this in inefficient.
