Data Classification and Tolerance Analysis
Critical systems, data volumes, daily change rates, and service dependencies are determined to define RPO (maximum data loss period) and RTO (maximum interruption period) metrics.
Backup system installation is a service that ensures critical data, databases, virtual machines (VMs), and SaaS workloads are automatically copied, encrypted, stored, and regularly tested for restoreability according to defined RPO (Recovery Point Objective) and RTO (Recovery Time Objective) targets.
In modern infrastructures, simply having a backup is not a security guarantee; the critical aspect is how quickly the data and services can be error-free restored when needed. Unconfigured, on-site or same storage unit backups can lead to irreversible data loss in the face of ransomware attacks or hardware failures.
During the process, a 3-2-1-1-0 backup rule is established for virtual machines (VMware/Hyper-V), relational databases (PostgreSQL/MSSQL/MySQL), file servers, and cloud/SaaS services. A immutable backup (unchangeable backup) against deletion, off-site/S3 object lock copies, end-to-end AES-256 encryption, storage policies (retention), and automated restore validation scenarios are included.
Critical systems, data volumes, daily change rates, and service dependencies are determined to define RPO (maximum data loss period) and RTO (maximum interruption period) metrics.
A 3-2-1-1-0 rule-compliant architecture with different storage environments (NAS/SAN/Tape/S3 Cloud Storage), immutable storage, retention periods, and encryption architecture is designed.
Automated backup jobs with Veeam, Bacula, etc., are set up, including incremental/full backup schedules, AES-256 encryption keys, and capacity/failure alert mechanisms.
File-level recovery, database point-in-time recovery, and full system (Bare-Metal / Instant VM Recovery) recovery scenarios are simulated and verified.

The 3-2-1 rule refers to having at least 3 copies of data, stored in 2 different types of environments (e.g., NAS and Cloud), and at least 1 copy off-site (Off-site). The advanced 3-2-1-1-0 approach adds that 1 copy must be immutable/offline and the restore must be automatically verifiable without errors.
No, a snapshot is not a backup. Snapshots are temporary states that provide quick recovery in short-term hardware/software changes. They become unusable when the main storage (SAN/Datastore) fails or when ransomware infects the system.
Restore tests should be performed based on the criticality of the data and should be repeated at least every quarter (3 months) or after critical infrastructure updates. Untested and unverified backups are considered non-functional in disaster scenarios.
