Of course, I meant "annoying" in a good way ;)
Yep, 'xz' was missing, libs were there but not the compressor
[root@engine1 ~]# rpm -qa | grep xz
xz-libs-4.999.9-0.5.beta.20091007git.el6.x86_64
Installed package xz
[root@engine1 ~]# rpm -qa | grep xz
xz-4.999.9-0.5.beta.20091007git.el6.x86_64
xz-libs-4.999.9-0.5.beta.20091007git.el6.x86_64
Backup worked like a charm. Cheers

Been trying to run a complete backup on a fresh install to get rid of

Well, I hope you prefer that over not be able to restore you engine if it dies :-)

Believe me, this was done after real people lost data and time, not because anyone found
it fun to do.
engine-backup --scope=all
Kept failing with the error:
2016-04-17 04:05:31 8742: Creating temp folder

Perhaps it's because you do not have 'xz' installed, and engine-backup
defaults to use xz for the --files-compressor?
It will be fixed in 3.6.5, where engine-backup is packaged separately, with proper
'Require:' lines in the spec file:
https://bugzilla.redhat.com/show_bug.cgi?id=1320092
https://gerrit.ovirt.org/55045
Please try installing 'xz' and run engine-backup again. If it fails, please report
back. Thanks.
Research shows a bug reported on version 3.6.0 related to the tar
options
https://gerrit.ovirt.org/#/c/48596/3/packaging/bin/engine-backup.sh
https://bugzilla.redhat.com/show_bug.cgi?id=1282397
But a grep of the script shows the changes have been made
[root@engine1 iso]# grep cpSs
/usr/share/ovirt-engine/bin/engine-backup.sh
[root@engine1 iso]# grep cpS
/usr/share/ovirt-engine/bin/engine-backup.sh
tar -C "${dir}" -cpS"${ARCHIVE_COMPRESS_OPTION}"f
"${file}" .
>> "${tar_log}" 2>&1
tar -C / --files-from -
-cpS"${FILES_COMPRESS_OPTION}"f "${target}" || logdie "Failed
backing up ${paths}"
Verified I had a new version (just re-installed ovirt-engine today)
ovirt-engine-3.6.4.1-1.el6.noarch
Linux engine1.attlocal.net 2.6.32-573.22.1.el6.x86_64 #1 SMP Wed Mar

Then I noticed there is an option to turn off –files-compressor.
Doing this I was able to get a complete backup.
[root@engine1 iso]# engine-backup --mode=backup --scope=files
--file=/mnt/h97m/backup_files_20160417
--log=/root/backup_files_20160417.log --files-compressor=None
Backing up:
Notifying engine
- Files
Packing into file '/mnt/h97m/backup_files_20160417'
Notifying engine
Done.
That's an option too.
And you do not loose much by using it, because the files tar is compressed anyway when the
archive is compressed, using gzip by default. 'files' are usually very small,
compared to the databases, so the difference is not significant.
Best,
