Local VMWare storage full can't execute prune.

When trying to create a prune rule set I get this error message:

~ # vertical prune -k 7:9
Vertical Backup 1.0.0
Storage set to sftp://user@111.111.8.55//home/vmwarebackup
No previous fossil collections found

Failed to save ‘/opt/verticalbackup/.verticalbackup/cache/chunks/70/51/cfb32c13dbc907accd90ab29272c4b60debc0ab7b17ecc5ddd54edb175ef.77a14cf1’: No space left on device

So I look at the VMWare host and I indeed see limited storage on the local OS mount:

Filesystem Size Used Available Use% Mounted on
VMFS-5 131.0G 129.1G 1.9G 99% /vmfs/volumes/OS
VMFS-5 953.0G 684.1G 268.9G 72% /vmfs/volumes/Datastore
vfat 4.0G 26.5M 4.0G 1% /vmfs/volumes/514066cf-c4b82650-7eb0-90b11c2d6862

What is being stored locally versus the remote storage? (which I set up there b/c it has TB of space available). How can I clean this up and free up local space without hosing any of the backups?

The default cache location is /opt/verticalbackup/.verticalbackup/cache. It is used to stored temporary copies of the backup index files so Vertical Backup doesn’t need to download them every time it runs the prune command.

You can rerun the init command with the --temp-dir option to change this default cache location to a folder under the datastore:

./vertical init hostid storage_url --temp-dir /path/to/local/datastore/verticalcache
