Backup Exec 11d backup to disk file size

Experts,
I am in the process of setting up Backup Exec 11d and am confused about setting the file size of a backup to disk file. The default size is 1GB. If I create a backup that is 200GB in size, does that mean that my backup to disk folder will have 200 backup to disk files in it?

The Backup Exec documentation does not give any guide lines that I can see on what an optimal size for the files would be for various environments. It only warns you that before you change the default file size, you should be aware that making many small files could effect system perfomance, and that making the file size too big could effect file system limitations and network perfomance.

Question is, what is an optimal file size for an environment with a 200GB+/- weekly backup job? I'll be backing up to disk on the same server that Backup Exec is running.

If you can help me understand this, I would greatly appreciate it.

Thanks,

As BE does compression, you'll get less than 200 files, but yes, you'll get a bunch of files of 1GB size each. I'd leave that size as it is, as you can copy the files to different media formatted in different filesystems, some of which have restrictions in the max size of a file. Also, if a file in a backup goes corrupt, you should still be able to recover most data, while if you just have one large file and that goes corrupt, the complete backup is dead.

So my backup job will span multiple files, correct? Does that mean that I will have to catalog each one individually?

Yes, and no. The files have a common filename and just the extension is different (filename.001, ...002, ...003 and so on).
