Perhaps a better example would show the same operation used on multiple folders

# tar -cf – /var/www /var/ftp | split -b 100m – my_backup.tar

To guard against missing or damaged pieces, install “par2cmdline”, and create parity files so that you can repair missing pieces.

To create parity files with a 15% redundency:
# par2 create -r15 my_backup.tara*
To verify:
# par2 verify my_backup.taraa.par2
To repair missing pieces:
# par2 repair my_backup.taraa.par2
To combine the pieces and extract:
# cat my_backup.tara? | (tar x)

Perhaps I am missing something. For a single large file why not simply use the split command by itself? Executing a single command might be faster than executing both tar and split.

split –bytes=1024b sdbackup.db db_backup_
cat db_backup_* > joined_file.db
