I'm trying to backup my cluster via cbbackup. I start the backup via

/opt/couchbase/bin/cbbackup couchbase://Administrator:password@mymachine:8091 /backups/couchbase_backup_test

The backup appears to work fine and a progress bar appears, but then exceeds 100% progress and never stops! Example:

^Cinterrupted.###############################] 210.8% (26141950/12403784 msgs)

(I ctrl-C'd to kill it after 200% because it seems that this can't possibly work. Note that both the percent and the number of messages are off). I only have ~12 million items in the bucket, but it went right past that limit when backing up.

Help?

One of our engineers just started looking at this issue and wasn't able to reproduce it. Can you provide details on what was going on in you system during the backup process since our setup might have been different than yours. What was the workload like? How many servers in your cluster? What os are you running on? And is there any other useful information you might have to help us reproduce the issue?

The test case was pretty simple:

- couchbase 2.0.0-beta release
- ubuntu 11.10
- only a single server in the cluster
- zero workload, aside from the backup itself

My objects were simple java objects of a couple hundred bytes each, and I was testing with several dozens of millions of them.

The problem went away once I started referring to the remote machine by IP address rather than hostname, so maybe this is a non-issue.

Same problem and same set up. I had a single instance running on the 2.0.0-beta on Ubuntu 11.10 and got the same infinite loop.

Hello,

Can you move the the Couchbase Server 2.0 GA?

The 2.0 official release has been published on Dec 12th, and it is probably a good idea to test with the latest one.

Regards
Tug

I was in the process of doing that when I hit this issue. :) I'm now on the GA release, but I lost the data I had in the beta version (or I have the data files, but I can't load them). Not a big deal, I guess that's just the cost/risk of using beta software.
