1. Could you please clarify, is it possible to perform a backup with read-only user ?
Read only user could run backup only on default bucket or any bucket with empty password.
Bucket with password protested, read only user could not run backup."
As a result of backup with credentials of read-only user I see this line in stdout
Error with backup for running “/opt/couchbase/bin/cbbackup” -v -t 1 --vbucket-list=[0,1,2, …
And auth-error in particular-backup-err-log (bucket_name is a name of bucket that is password-protected):
error: SASL auth failed: host_name:11210, user: bucket_name
So, is last comment in https://issues.couchbase.com/browse/MB-13536 correct, and if it is, don’t you think, that such behavior is … at least “weird” and, probably, should be a subject to change ? @ingenthr, @mikew ?
2. What is a good criteria to post-check cbbackupwrapper output and ensure that backup is completed without errors ?
For example, with read-only user i see “Error”-containing-lines, but, anyway, the last stdout line is “SUCCESSFULLY COMPLETED!”. So, what should i rely on (when checking output) to be sure, that “backup is completed without errors” ? (this is needed for deferred automated check)
+UPDATE: very often (too often) backup ends with (or shows-in-process) messages like:
Exception in thread Thread-1 (most likely raised during interpreter shutdown):
Traceback (most recent call last):
File “/usr/lib/python2.7/threading.py”, line 810, in __bootstrap_inner

File “/usr/lib/python2.7/Queue.py”, line 174, in get
< type ‘exceptions.TypeError’ >: ‘NoneType’ object is not callable
is it normal ?
Yes, i can use -P 1, but of course i would like to use more threads then 1
