CLI:Error Utility Name Empty when try to use backup gem

[franciscopaniskaseker]

What went wrong?

When I try to execute some backup commands I am receiving CLI Error.

What steps did you follow?

[root@ models]# backup check
[2017/07/06 12:41:44][error] CLI::Error
[2017/07/06 12:41:44][error] --- Wrapped Exception ---

[root@ models]# /usr/local/bin/backup perform --trigger sql --tmp-path /home/tmp/

How is your copy of backup configured?

I already tried new (from zero) config.rb file. I already tried create new models (follow official documentation). If I put the model name, I get error. If I do not write, it will fail (as we expect).

[root@wither models]# /usr/local/bin/backup perform --trigger 
No value provided for option '--trigger'

[root@wither models]# /usr/local/bin/backup perform --trigger sql
[2017/07/06 12:46:42][error] CLI::Error

I already tried remove backup gem and reinstall from zero without success.

Hello @franciscopaniskaseker,

OK, please which can you double-check that mysqldump is installed and where it should be? e.g.:

which mysqldump

Next, please can you post an example of the config and model files as a gist? I can then investigate further with you.

[franciscopaniskaseker]

[root@ ~]# whereis mysqldump
mysqldump: /usr/bin/mysqldump /usr/share/man/man1/mysqldump.1.gz

[root@ ~]# mysqldump
Usage: mysqldump [OPTIONS] database [tables]
OR     mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
OR     mysqldump [OPTIONS] --all-databases [OPTIONS]
For more options, use mysqldump --help

[root@ ~]# which mysqldump
/usr/bin/mysqldump

Now a SQL backup example:

Model.new(:sql, 'dump sql') do

        database MySQL do |db|
                db.name         = :all
                db.username     = "root"
                db.password     = "*******"
                db.host         = "localhost"
                db.port         = "3306"
                db.socket       = "/var/lib/mysql/mysql.sock"
                db.prepare_backup       =       true
                db.additional_options   =       ["--quick", "--single-transaction"]
        end

        #compress_with Gzip

        compress_with Custom do |compression|
                compression.command = 'pxz -k -6 -T2'
                compression.extension = '.xz'
        end

        store_with Local do |local|
                local.path = '/backup/sql'
                local.keep = 160
        end

        Logger.configure do
                logfile.enabled   = true
                logfile.log_path  = 'log'
                logfile.max_bytes = 500_000
        end
end

We used this script since 2017 January without changes. Backup stopped since 9th June.

OK, thank you. Have you tried without the custom compression? That could also raise the "Utility Name Empty" error.

[franciscopaniskaseker]

I removed custom compression and I get same error. I have others servers using same version without problem even with CentOS x86_64 7.3.1611.

I compared ruby version and gems and they use same versions. I wondering if I have some environment variable causing this.

I am not expert with ruby on rails environment, but If reinstall ruby and backup gem (config from zero, ie, without reuse config files) did not work, probably I have environment issues.
