Which Backup Command Is Correct?

[Rhughes]

If I read the Hindsdale How-to instructions for performing a single-drive backup on a Series 2 (R10), it shows the following command:

mfsbackup -f 9999 -6so /mnt/dos/tivo.bak /dev/hdc

However, when I read the Weaknees Interactive instructions for the R10 it shows the following:

mfsbackup -f 9999 -1so /mnt/backup.bak /dev/hdc

My question is mainly the difference between -6so and -1so. Is this just a difference between the Hindsdale and Weaknees software?

I also notice that the Weaknees instructions say nothing about unmounting the drives. Is this also a difference in the software?

Either setting will work fine and you should unmount the drives before shutting down.

the -1 or -6 sets how much compression will be used for the backup file it creates. I think the higher the number, the higher the compression and the smaller the backup file will be. I think the higher compression rates takes longer to create.

On some computers a backup made with the compression value of 6 will not restore correctly.
