Hi All,

Iâm having issues using the engine-backup command.

When running:

engine-backup --mode=backup --scope=files âfile=veng.bak --log backup.log

I get back the following error:

readlink: missing operand

Try 'readlink --help' for more information.

/usr/bin/engine-backup: line 1405: : No such file or directory

Notifying engine

/usr/bin/engine-backup: line 1472: : No such file or directory

/usr/bin/engine-backup: line 1405: : No such file or directory

FATAL: Failed notifying engine

Log file is not created.

I receive similar errors when changing the scope to âall' and âdb'.

Iâm running:

CentOS Linux release 7.2.1511 (Core)

oVirt Engine Version: 3.6.2.6-1.el7.centos

Engine is running on bare metal.

I have tried this with SELinux in Permissive mode. No difference.

All packages are up to date.

Can anyone advise a fix for this or if Iâm doing anything wrong?

Thanks in advance,

Please try '--log=backup.log' (with '=').
That was unfortunately only a typo in the email. And not when running the actual command.

You have an EM DASH (U+2014) instead of two HYPHEN-MINUS (U+002D) in front
of 'file='.

Where did you copy that command from?

I suspect that my Outlook client for Mac has done that.

Where did you copy that command from?

From my command line.
I have attached the command including the entire output in plaintext.

I get back the following error:

Now copied the command from the attached file and it worked for me.

If it still does not work for you, please run this:

BACKUP_ENV_CLEAN=1 sh -x /usr/bin/engine-backup --mode=backup --scope=files
--file=veng.bak --log backup.log > engine-backup-out 2> engine-backup-err

and check/post engine-backup-out and engine-backup-err (as links to some
pastebin service, please).

Thanks for your help Yedidya! The issue went away after a fresh engine install on my new hardware.
