Disaster
Recovery

Hope is not a strategy. We engineer immutable backups, off-site replication, and high-availability clusters to ensure your 'Golden Image' can survive ransomware, hardware failure, or catastrophic data loss.

Architectural Backups

Standard file-level copying is slow and leaves databases in inconsistent states. We engineer bare-metal backup strategies to ensure perfect consistency and rapid restoration.

Immutable LVM/ZFS Snapshots

We freeze the disk state at the block level in milliseconds. This guarantees your MySQL/PostgreSQL databases are captured perfectly without shutting down your web applications.

cloud_sync

Off-Site Rsync Replication

Snapshots are strictly useless if stored on the same server. We automate incremental, encrypted transfers of your data to completely isolated storage vaults in geographically separate datacentres.

restore_page

Rapid Bare-Metal Restores

If your server suffers a catastrophic hardware failure, we do not waste time rebuilding the OS. We restore the exact byte-for-byte image of your system to fresh hardware, minimising RTO.

enhanced_encryption

Ransomware Air-Gapping

Modern ransomware seeks out and encrypts attached backups. We construct "pull-only" backup architecture, meaning the production server has zero access to the secure backup vault.

alt_route

High-Availability Failover

For systems where 10 minutes of downtime is too much. We engineer active-passive nodes using Keepalived and HAProxy. If node A fails, node B instantly assumes the floating IP address.

fact_check

Automated Integrity Audits

A backup is only theoretical until it is tested. We configure automated scripts to trial-mount and verify the checksums of your backup archives, alerting our NOC if data corruption is detected.

Disaster Recovery FAQ

Authoritative answers regarding our backup methodologies, recovery times, and ransomware defence architecture.

What is an RPO and an RTO? expand_more

RPO (Recovery Point Objective) dictates how much data you can afford to lose (e.g., if backups run hourly, your max data loss is 1 hour). RTO (Recovery Time Objective) dictates how long it will take us to get your systems back online after a failure. We engineer the architecture specifically to meet your business SLA for both metrics.

How do immutable backups protect against ransomware? expand_more

We configure your storage to be "read-only" and append-only at the vault level. If a threat actor compromises your primary server, they cannot SSH into the backup vault to delete or encrypt the remote archives. The backup server "pulls" data; the compromised server cannot "push" a deletion command.

Will snapshots slow down my database performance? expand_more

LVM (Logical Volume Manager) snapshots operate at the block level. The initial "freeze" takes milliseconds, preventing database table locks or dropped connections. The system continues running smoothly while the background `rsync` process replicates the snapshot payload over the network.

Where are the backup vaults located? expand_more

To ensure physical redundancy, your off-site backups are transmitted to an entirely separate, ISO 27001 compliant datacentre. For our Irish clients, primary nodes are typically in Dublin while the vault is located in Frankfurt (or vice-versa), ensuring strict EU data sovereignty.
