Back up at the  container level. This is a more complex way to back up the containers and their data: GLYPH<SM590000> You still must do the instance-level backup, in case you must recover  zCX itself. GLYPH<SM590000> But to recover single containers without affecting the other containers  that run in this zCX instance, you must have additional backups. Option Details 7.3.1 Backup and recovery on zCX instance level Data belonging to a zCX instance The instance-level backup is a very convenient way to back up and recover a full zCX  instance with all containers that run inside it. It is especially suitable to handle a zCX instance  that matches one of these descriptions: GLYPH<SM590000> Only one container runs in it. OR GLYPH<SM590000> All containers that run in it belong to a single application. All data that makes up a zCX instance lives within the VSAM linear data sets that have  been defined by the provisioning or the add-volume workflows. These VSAM linear data  sets are the ones whose name starts with the high-level qualifier for this zCX. This qualifier  is set during the provisioning workflow. Example 7-20 shows a list of these data sets.

GLYPH<SM590000> The properties file of the instance.  Except for the  start.json  file that is needed for the start of zCX, these files are not used at run  time but rather for the z/OSMF workflows to maintain the zCX instance.
