Free disk space is greater than two times the size of the last backup, but backups are going into failure.

By default, the threshold to stop backups from working is 90% (0.90) of the partition.

  1. Watch for similar dashboard notifications:
    Disk Sentry: Disk Usage exceeded warning threshold

  2. Verify that your disk space is under 90% on your NFS share.

    Use the mount point ( /nfs) change directories by using the cd command to verify that you have connectivity.
    cd /nfs

    Type du -sh to see how much space is being used.

  3. Perform clean up of your NFS share by doing the following.

    • Remove any unnecessary files from the NFS share so the disk space is under 90%.

    • Clean any old backup from the NFS share by coping it to another storage device or removing per your required retention policy.

    • Log in to the JSA User interface.

    • Open the Admin settings: In JSA V7.3.0 or earlier, click the Admin tab.

    • Click Backup and Recovery icon.
      Option 1 Change Backup Retention --> Click Configure --> Change the Backup Retention period days to a shorter interval.
      Option 2 Delete backups --> Click on the backups to delete --> Click Delete.

    • Click on the backups you have copied off the NFS share.

    • Click delete the selected Backups.

    • Verify the space on the NFS share is under 90%.

With the NFS Share disk space under 90% your backups should complete successfully.
