# Revised 2013-09-25, Brian Martin, as follows: |
| 52 |
# - Allow retention period ("DAYS") to be specified as a parameter. |
| 53 |
# - Allow individual positional parameters to be left at the default |
| 54 |
# by specifying "-" |
| 55 |
# - Use IS0 8601 standard dates (yyyy-mm-dd instead of mmddyyyy). |
| 56 |
# - Display tar exit codes when reporting errors. |
| 57 |
# - Don't send error messages to /dev/null, so we know what failed. |
| 58 |
# - Suppress useless tar "socket ignored" message. |
| 59 |
# - Fix retention period bug when deleting old backups ($DAYS variable |
| 60 |
# could be set, but was ignored). |
