The SDDC Manager configuration backup fails at 80% with the error: "Package and encrypt SDDC Manager backup failed."
SDDC Manager 5.2.x
Placing an upgrade bundle or any file in /opt/vmware/vcf will significantly increase the configuration size, which causes the default backup location at /var/log/vmware/vcf/sddc-support to run out of space and will eventually lead to a backup failure.
/opt/vmware/vcf directory for any large files by running the command:
du -sh *
rm -rf <File-Name>
Note: Do not move any files to /opt/vmware/vcf, as this location is included in the SDDC Manager backup.
