Disk space management for instances
Citrix Adaptive Authentication team manages all upgrades and maintenance of Adaptive Authentication instances. Therefore, it is recommended that you do not upgrade or downgrade the Adaptive Authentication instances to random RTM builds. Citrix manages the Adaptive Authentication instances, by default.
For the instance upgrades, a minimum of 7 GB space is required in the VAR directory. Therefore, the Citrix Adaptive Authentication team clears the disk space on the instances before applying upgrades. It is recommended that you do not keep any sensitive, proprietary, or personal information in the following directories:
The /var/nsinstall directory is cleared first during the upgrade followed by the /var/tmp directory.
If the minimum space requirement is still not met, then the other directories (/var/core, /var/crash, /var/nstracem, and /var/nslog) are cleared as well.
Option to manage disk space yourself
Though Citrix manages the Adaptive Authentication instances, by default, you can prefer to clean up the disk space on the instances yourself. You can opt out of the default method by doing the following:
In the Adaptive Authentication navigation pane, click Instance Management.
Select I prefer to manage diskspace myself and then click Confirm in the confirmation message dialog box.
Click Save Changes.
You can also schedule upgrades according to your customer traffic. The Citrix Cloud team then upgrades your instances accordingly. For information about scheduling upgrades, see Schedule upgrade of your Adaptive Authentication instances.
