A list of known issues and limitations with the current release are provided within this section.
2.5.0
Release Date
2021-09-08
What's New
1.
Immutability: Trilio provides the ability to create immutable backups at the application level. Once the backup is taken and stored on an immutable target, it can not be altered (overwritten/deleted) until the retention period set through TVK is up.
2.
Encryption/Decryption: Added support to encrypt backups to protect them from malicious users. TVK encrypts the backup data at the application level using an encryption key which can only be restored with the same encryption key. Even if an attacker gets holds of the backup data he can not see the actual data without a key.
3.
Multi Namespace Backup/Restore: Earlier TVK used to protect only a single namespace with a single backup plan. Now, you can protect multiple namespaces using new CRDs - ClusterBackupPlan, ClusterBackup, and ClusterRestore.
4.
NFS target without privilege: Earlier TVK requires NFS target to be mounted with privilege permissions, now for NFS target we have removed privileged access. This allows TVK to be run in an restricted environment without escalated permissions.
5.
Inclusion/Exclusion: You can provide specific resource which needs to be included or excluded while doing backup. Resources can be specified either by GVKO or by the Kind directly.
6.
LDAP & OIDC Support: TVK support 8 tested popular public OIDC providers including Google, Github, Azure, Okta, GitLab, LinkedIn, and ideally any OIDC provider will work.
7.
OpenShift Authentication Support: This is enabled by default on OpenShift platform with the TVK operator. Trilio will auto-configure the management console based on authentication mechanisms available within OpenShift
8.
Protect Restored Application: Recreate targets, policy, hooks, and backupplans to protect the restored application. Now, the application is protected no matter the Kubernetes cluster it is restored into.
9.
Failed Restore Cleaner: Now restore allows you to specify via a flag to clean the resources created by the restore, if the restore fails.
10.
Krew Plugin for target browser: TVK now has the kubectl plugin to get the backup information from the target using the kubectl CLI.
11.
Target Credentials as Secrets: Earlier TVK used to have naked authentication information inside the target CR. Now, we support the target credentials to be saved as a secret and refer to the target CR for better security reasons.
12.
Scheduling as a Policy: Now you can define the backup schedule policy as a different policy object and can use a policy in different backupplans.
13.
Azure blob storage support: Added support to use the Azure blob storage as a target. We are using NFS3.0 to use the Azure blob storage.
14.
S3 SSL Certificate: Now we support authenticating S3 targets using SSL certificates.
15.
ReadOnlyRootFilesystem: All the containers that are running as backup and restore processes are running with a readOnlyRootFilesystem.
16.
Sharing of Resources: To enable simplified management of Trilio resources in a multi-cluster environment, users can share/clone resources like targets, hooks, policies, etc. across namespaces in the same cluster or across clusters themselves.

2.1.0
Release Date
2021-05-04
What's New
1.

2.
Multi Cluster Management: TVK now supports managing multiple TVK clusters/installations through the UI.

4.
Analytics Controller: TVK now comes with an analytics controller which populates running stats in trilio resources providing extra information about individual resources.
5.

Datamover Performance: This release includes performance improvement to the NFS based targets
8.
Lightweight webhook & OLM bundle: TVK has simplified installation process by moving resource creation to it's Helm chart and the OLM bundle, making the webhook init process lightweight
9.
View/Download YAML: Ability to view raw YAML files for Backup, Restore, Backupplan, Target, Hooks,Retention Policy.
10.
DR Plan: Disaster Recovery Plan feature to support a plan via a single workflow to recover your cluster state in case of any disaster.

Kubernetes 1.20 adds a new field known as ClusterIPs for the service resource that is auto-populated from the clusterIP field. Trilio wipes out the clusterIP field from a service resource before a restore, but the ClusterIPs field cannot be non-empty with the clusterIP field. As a result, the restore validation fails. Trilio will fix this issue in a subsequent release, but until then restore transformations can be used to workaround this issue. A video explaining the transform can be found here

0.2.3 - 0.2.5
1.
Issues post uninstall:
1.
MutatingWebhookConfiguration and ValidatingWebhookConfiguration is not cleaned up
2.
The Cleaner cronjob is not cleaned up.
3.
Cleaner cronjob will fail to create jobs due to RBAC revocation
4.
In case of scheduled backups defined for any BackupPlan, the cronjob for the same will not be cleaned up unless the BackupPlan is deleted. This will lead to failed jobs due to RBAC revocation
Helm charts with sub-charts are not yet supported
2.
In case there is a problem with Target after it is created (change in IP, removal of keys in use), it won’t change the state of Target and will still show Available
3.
OCP UI forms should not be used for resource creation. Instead, the YAML/JSON editor should be used
4.
Listing CRD resources don’t show correct status on OCP UI for operator details
5.
OLM does not consider the scope of CRD it is installing.
1.
Problem: In case TrilioVault is installed in cluster scope and then deleted and after then if the user tries to install in namespaced scope, OLM allows it. On operator deletion, CRD’s are not deleted. So even when the user did the namespaced installation, the underlying CRD’s are installed in cluster scope, leading to issues with application functioning
