Hi, some of you have reported problems and / or solutions regarding our Percona / xtrabackup plugin.
I want to summarize some pitfalls and hints here. 1. Always incremental only works with file backups A user reported problems like this https://github.com/bareos/bareos-contrib/issues/33 on github Please do not use Always Incremental with plugins as this won't work by design. Compare documentation: http://doc.bareos.org/master/html/bareos-manual-main-reference.html#AlwaysIncrementalConcept 2. Restore via webui does not work with (some) plugins some people here have reported problems on restore like 2018-09-19 17:55:05 | bareos-fd JobId 1896: Error: python-fd: No lsn information found in restore object for file /tmp/bareos-restores//_percona/xbstream.0000000355 from job 355 As of now, the web UI does not ensure to restore extra information called "restore object". Plugins that rely on these kind of extra-information will fail on restore. This problem was also reported for the VMWare plugin and a bug-report exists: https://bugs.bareos.org/view.php?id=805 Thanks to Geoffrey McRae for reporting this and sending a patch / pull request. We will evaluate this pull request and include it, unless we find any side-effects. Please follow the pull-request to get updates on this issue: https://github.com/bareos/bareos/pull/119 Workaround: use bconsole to select files for restore, when plugins are involved in the restore process. 3. Restore problems with filesets containing File = .. AND Plugin = .. directives When using filesets with plugins and files mixed, like File = /etc Plugin = "python:module_path=/usr/lib64/bareos/plugins:module_name=bareos-fd-percona" You might get errors on restore. If you choose to restore both - plugin data and files - and files are included in incremental backups, you may hit error messages like 2018-10-09 15:25:15 10.20.240.244-fd JobId 43240: Error: filed/fd_plugins.cc:1247 Unbalanced call to createFile=0 0 We will work on a fix. Please observe bug-report https://bugs.bareos.org/view.php?id=1021 Workaround: - use dedicated filesets when using plugins - try to restore plugin and files separately (not verified that this works under all circumstances).
