CloudCasa

CloudCasa by Catalogic is a Kubernetes-native backup, migration, and disaster recovery platform built around five core values: easy administration, world-class reliability, fast backup and recovery with minimal system impact, an open storage model, and first-class support. Catalogic has spent over 25 years focused on data protection, and CloudCasa carries that same discipline into Kubernetes. What makes CloudCasa different: GUI-first, fast to deploy. Manage every cluster from a single dashboard, with setup typically done in minutes, not days. Snapshot-based backups with minimal impact. Persistent volume backups read from CSI snapshots by default, and clusters can run multiple backup, restore, and migration jobs concurrently to shrink backup windows. Storage-integrated disaster recovery. CloudCasa DR for Storage delivers low-RTO failover by using storage-layer replication instead of relying on backup restores alone. An open storage model. Bring your own S3-compatible object storage, Azure Blob, or NFS targets, with SafeLock and object-lock immutability for ransomware protection. No vendor lock-in on where your backups live. Responsive, expert support. Live chat, phone, and a dedicated support portal, backed by a team with 25+ years of data-protection experience. Built for the platforms you already run. CloudCasa protects managed Kubernetes services including Amazon EKS, Google GKE, Microsoft AKS, DigitalOcean Kubernetes, and OVHcloud Managed Kubernetes, along with distributions like Red Hat OpenShift, SUSE Rancher, VMware Tanzu, Mirantis Kubernetes Engine, Nutanix Kubernetes Platform, and Canonical Kubernetes. It also protects Kubernetes-native virtual machines running on KubeVirt, OpenShift Virtualization, and SUSE Virtualization/Harvester, and supports backup storage on Amazon S3, Azure Blob, Google Cloud Storage, Backblaze B2, Ceph, and other S3-compatible targets. Who it's for. Platform teams, DevOps engineers, and Kubernetes administrators use CloudCasa for day-to-day cluster protection. Managed service providers use it to deliver backup, migration, and DR as a service across tenant organizations. Business continuity teams rely on CloudCasa DR for Storage to meet recovery-time commitments without waiting on full restores from backup. How it compares. Teams often adopt CloudCasa after starting with open-source or CLI-based Kubernetes backup tools and needing a centralized, GUI-driven way to manage backup, migration, and DR across many clusters without building that tooling themselves. Compared to general-purpose enterprise backup platforms retrofitted for Kubernetes, CloudCasa is built Kubernetes-native from the ground up, with CSI-snapshot backups, Kubernetes-aware restore, and storage-integrated DR as core capabilities rather than add-ons. Common use cases. Cross-cluster and cross-cloud migration, ransomware recovery through immutable recovery points, namespace and file-level restore, and compliance-driven audit trails for regulated environments. Whether you're protecting a single Kubernetes cluster or running backup, migration, and DR across a fleet of clusters and clouds, CloudCasa gives Kubernetes platform teams and DevOps engineers enterprise-grade protection without enterprise-grade complexity.

Mirror Backup

Mirror Backup protects you from data loss by continuously monitoring files and folders, and backing them up to the cloud, a network share, or local drive when they change. It does this in a background service that does not require a user to be logged in - perfect for company servers. It can also keep incremental backups, when you want a history of each file's changes. In some situations, this design is more desirable than whole-disk backups. And if the worst should happen, you can restore a backup with just a few clicks.

RecordFlow

RecordFlow archives Zoom cloud recordings automatically to storage you own — Google Drive, Dropbox, Microsoft OneDrive, or S3-compatible storage (Amazon S3, Cloudflare R2, Backblaze B2, Wasabi, MinIO) — the moment a meeting ends. Connect once and never think about a manual download again. WHAT IT DOES - Moves each recording automatically within minutes of the meeting ending — nothing to remember, nothing to download by hand. - Handles large and password-protected recordings without extra setup, which is where most Zoom automation tools fail. - Renders Zoom's raw transcript into a formatted, readable document alongside the original. - Covers a whole team from one admin install: every opted-in member's recordings land in a shared root with a sub-folder per person. - Recovers from a failed transfer on its own — no manual retry, no lost recording. - Can delete the Zoom copy once the archived file is verified — freeing Zoom cloud storage with no manual cleanup. DESTINATIONS Recordings can go to Google Drive, Dropbox, Microsoft OneDrive, a private YouTube video, or S3-compatible storage (Amazon S3, Cloudflare R2, Backblaze B2, Wasabi, MinIO) — pick one when connecting. SECURITY Sign-in goes through Zoom and the chosen storage provider — RecordFlow never sees or stores a password. Recording bytes are streamed through and never written to disk on RecordFlow's infrastructure. Stored OAuth credentials are encrypted at rest. PRICING Full product, no time limit, at no cost: Zoom sign-in, automatic archiving to storage you own, transcripts, and email notifications. The one paid add-on — importing more than the past month of existing Zoom history — is a one-time $19 + VAT, paid once, no subscription.

Nota Backup & Restore

Nota Backup & Restore is a WordPress backup plugin that creates complete site backups — all files and the database — in a single ZIP archive and restores them safely with one click. It is built for reliability on real-world hosting: instead of trying to back up an entire website in one long request, it processes the backup in small chunks in the background, automatically tuned to the server's available memory. This means backups complete successfully even on inexpensive shared hosting with strict execution time and memory limits, where many other WordPress backup plugins fail with timeouts or corrupted archives. The free version, available on WordPress.org, covers the essentials: one-click full site backup, safe one-click restore, a backup history with download and delete options, and automatic detection and cleanup of failed or orphaned backups. It is lightweight and focused — no bloat, no account required, no lock-in. The premium version turns Nota Backup & Restore into a complete backup automation solution. Scheduled automatic backups run on multiple configurable profiles, so you can, for example, back up the database daily and the full site weekly. Finished backups can be uploaded automatically to six cloud storage destinations: Google Drive, Amazon S3, Wasabi, Dropbox, OneDrive, and FTP/SFTP servers. Backup archives can be encrypted with AES-256 for secure offsite storage. Email notifications report every backup success or failure, and a stale backup alert warns you if scheduled backups stop running. An emergency recovery tool can restore your website even when the WordPress admin panel is inaccessible. Nota Backup & Restore is designed for WordPress site owners, freelancers, agencies, and WooCommerce store owners who need dependable website backups, disaster recovery, and site migration without managing servers. Premium plans start at $39 per year for two websites and include a 14-day free trial with no credit card required.
