Fix documentation typo (accident quotes)
Add backup cleanup (bnc#896244). Moved to a separate class to move all other backup operations there in a future.
Use of backup cleanup.
No need to touch xlog as well as backup history files.
Check if the backup target directory has the same owner/permissions as the data directory.
Changed question message to be compatible with many options.
Forgotten whitespace.
When taking hot backup, no longer need to pass optional arguments.
Ban relative paths completely.
System check shall not kill backup setup.
Re-writing the same with regexps for easier understanding.
More explicit message for missing backup destination.
Removed unnecessary filtering.
Filtering is still needed to avoid wrong param selector when extra spaces are in the command.
