Best solution for Jenkins backup and restore

[gotvi...@gmail.com]

Hello All,

I have been surfing around for this stuff for quite sometime and till now couldn't find a plugin that does this job seamlessly.  I tried these options - SCM Sync Configuration plugin, ThinBackup plugin and PeriodicBackup plugin.  

PeriodicBackup plugin seemed nice as it was giving option for full backup which is what we are also looking for.  But, it doesn't seem to work properly.  As per the backup configuration I limited it to 5 maximum backups and 5 days to store the backup.  But, it doesn't stop with 5.  It keeps adding the new ones as per cron, but not deleting the old ones.  Also, the restoration doesn't work at all.

But, with ThinBackup and SCM Sync Configuration plugins we have a limitation of not being able to backup the entire JENKINS_HOME folder.

Does anybody have a best possible solution for this?  I had couple of suggestions for rsync.  But, wondering if that's the only way to do it or if there's any other easier backup/restore option that am missing.
