TKLBAM fails with error

Hi,

First time using TK Linux and generally very impressed.  I'm using TK Linux 12.0 for Rails.  

However, a couple of issues:

1. DHCP failed on my home setup using a WRT54G with Tomato 1.19 (WiFi access point firmware) - static was fine though.

2. TKLBAM fails to complete - this is more serious as the main reason I am using TK Linux is for the TKLBAM migration scenario

I'm on a DSL connection with about 1 Mbps upstream, and it's working fine while the backup was being run.

Is there a log file somewhere?  Seems like there should be by default ... if not, how do I enable one?

Bump

Any comments on this?  I'm not the only one with TKLBAM problems, which is a shame since I signed up for a plan based on TKLBAM, but haven't been able to use it to migrate from a local VM to EC2, which was the main draw of using TK Linux.

Is there a log file I'm missing here?

Same / similar problem here

Hello

I'm afraid won't be of much help but I have a very similar problem with my TKL based server for about a month. Just realised the backup are failing (there is not obvious warning - you really have to dig into the logs).

I'm going to investigate a report my findings.


more log info

Hi Alexandre,

Thanks for the comment - I am getting some successful backups but about 50% fail.  Must be something to do with TKLBAM or S3 (using eu-west since that's where my EC2 instances are).

From /var/log/tlkbam-backup:

Hmmm....

Obviously from your logs S3 is timing out. Why that would be occurring though I have no idea. Have you tried contacting the devs directly using the Hub Feedback (blue button on the left hand side)? Might be worth a shot. Maybe they have some ideas of where your problems may be?

I have contacted the

I have contacted the developers, and they are looking into this.  

What might help in diagnosing this is a simple ping test to the s3 host, though I suspect this is a service level issue.

My TKLBAM backups from a couple of EC2 instances have not failed, so clearly it is something to do with network path - but all other network activity from the VM + laptop is quite reliable, with only very occasional dropouts that should be resolved by the 5 retries for S3.
