# Revised 2013-09-25, Brian Martin, as follows:
|
|
# - Allow retention period ("DAYS") to be specified as a parameter.
|
|
# - Allow individual positional parameters to be left at the default
|
|
# by specifying "-"
|
|
# - Use IS0 8601 standard dates (yyyy-mm-dd instead of mmddyyyy).
|
|
# - Display tar exit codes when reporting errors.
|
|
# - Don't send error messages to /dev/null, so we know what failed.
|
|
# - Suppress useless tar "socket ignored" message.
|
|
# - Fix retention period bug when deleting old backups ($DAYS variable
|
|
# could be set, but was ignored).
|
|
