Understanding Benchmarks

I need a little clarification in understanding why there would be a need for a benchmark file when used with a backup script. Logically thinking would tell me that the backups itself(backuptest.tgz) would have the time created and etc. So what would be the purpose of such a file:

touch .benchmark

The backup files may be deleted, dumped on tape and put in a fire safe, or what have you. Why keep them on the same system?

thanks for the reply. I think I confused you. This is what I am talking about

if [ $level = 0 ]; then
  touch $benchmark
  $TAR czXf $excludefile - `cat $includefile`
  # -N arg must start with dot to be interpreted as a filename
  $TAR czNXf ./$benchmark $excludefile - `cat $includefile`

They create a .backup_benchmark before the backup is created. Why is that?

They use the -N option, to archive files newer than the benchmark file. So next backup they take, avoids previously backed up files.

I have created a script that performs that same function but I use find and CPIO instead, so just to make sure, I dont need a benchmark file if I am using:

Full Backup Stuff

sudo find /home -depth ! -path "*/\.*" -print| grep -f includefile | grep -v -f excludefile

Incremental Stuff

sudo find /home -depth -mtime 0 ! -path "*/\.*" -print | grep -f includefile | grep -v -f excludefile

find isn't psychic, it won't know when you took your last backup.
