Prune Inventory Backup Archive

The inventory backup archive will require maintenance over a long enough period of time.

Bulk pruning

It is possible to do mass pruning of the inventory backup. The following example will prune all but the last 15 inventories from the running archive.

ARCHIVE="/etc/openstack_deploy/backup_openstack_inventory.tar"
tar -tvf ${ARCHIVE} | \
  head -n -15 | awk '{print $6}' | \
  xargs -n 1 tar -vf ${ARCHIVE} --delete

Selective Pruning

To prune the inventory archive selectively, first identify the files you wish to remove by listing them out.

tar -tvf /etc/openstack_deploy/backup_openstack_inventory.tar

-rw-r--r-- root/root    110096 2018-05-03 10:11 openstack_inventory.json-20180503_151147.json
-rw-r--r-- root/root    110090 2018-05-03 10:11 openstack_inventory.json-20180503_151205.json
-rw-r--r-- root/root    110098 2018-05-03 10:12 openstack_inventory.json-20180503_151217.json

Now delete the targeted inventory archive.

tar -vf /etc/openstack_deploy/backup_openstack_inventory.tar --delete openstack_inventory.json-20180503_151205.json
