What's interesting is that cron ran my backup last night successfully... |
| 2 |
but didn't send the output to the log. |
| 3 |
|
| 4 |
I have lines like "logger "Server backup: blah blah blah"" in my script |
| 5 |
and I pipe the rdiff-backup output into logger as well. When I ran the |
| 6 |
script from the command line, the output showed up just fine in the log. |
| 7 |
But, when cron runs it, not a peep... and no dead.letter either. |
| 8 |
|

Oh well, at least my nightly backup is automated now. |
