I am using Jenkins v1.651.3 and to schedule automated daily backup I have installed the ThinBackup plugin v1.9. But when I trigger backup manually it does not work. In the system logs all I can see is -
Sep 01, 2017 9:31:37 AM INFO org.jvnet.hudson.plugins.thinbackup.ThinBackupMgmtLink doBackupManual
Starting manual backup.
Sometimes the backup process doesn't take place because of the directory permission issue.
Make sure that your Jenkins user has the write permission to the directory where you are trying to create your backup.
