# overwriting last weekly backups.
# The rest of the time an incremental backup is made. Each incremental
# backup overwrites last weeks incremental backup of the same name.
# NOTE: No incremental backup is made with MySQL dumps (full always)

# Using for 3 months this backup script since january you will have:
# January: PC-Jan08.tar.gz
# February: PC-Feb08.tar.gz
# March: PC-Dom01-FULL.tar.gz PC-Mon.tar.gz Pc-Tue.tar.gz ...
