Actually, the 2.6.0p2 release (and earlier) uses significantly different
values.
The maximum number of retries is only 5 and the resulting time is fairly
short (the backoff increases exponentially). I believe that 2.6.0p2 only
waits a a couple seconds
If the bucket you're trying to backup to isn't created yet, that's
probably the problem. If the problem persists, I'd recommend either
trying the beta or compiling a copy from source, tweaking the values in
device-src/s3.c .
I'm running 2.6.1b1 right now - I'm using the Ubuntu Hardy package for i386.
Specifically, you'd want to change the values
#define EXPONENTIAL_BACKOFF_START_USEC 10000
#define EXPONENTIAL_BACKOFF_MAX_RETRIES 5
to
#define EXPONENTIAL_BACKOFF_START_USEC G_USEC_PER_SEC/100
#define EXPONENTIAL_BACKOFF_MAX_RETRIES 14
I'll give it a try, but it's a bear to uninstall with the package and install from source - wish me luck!
