Коротка відповідь

Backup repository is not just big disk. It is retention, access, encryption, reports, transfer windows, restore tests and decision who can delete or shorten copy history.

Capacity with growth

Repository is calculated from full copy, daily increment, compression, short retention, long retention і restore-point count.

Retention і GFS

Many companies need daily, weekly, monthly and yearly copies. Cost and restore time must be calculated for every layer.

Separation і encryption

Repository should have separated accounts, encryption, access limits і clear procedures when client account is compromised.

Tests і reports

Project includes job reports, alerts, capacity trends, restore tests і regular review whether backup still matches business.

Практичний чеклист

  1. Calculate full copies, increments, compression, deduplication і real retention.
  2. Decide whether repository is shared, dedicated or connected with private cloud.
  3. Define encryption, access roles, account separation і emergency data unlock procedure.
  4. Design monitoring for capacity, errors, job duration і failed-backup alerts.
  5. Set restore-test schedule and periodic retention-policy review.

Can repository be dedicated?

Yes. For larger needs it can be dedicated or part of private cloud with separate access rules.

Does backup repository replace DR?

No. Repository stores copies, while DR describes service startup after incident.

Must backup be immutable?

It is worth designing mechanisms limiting deletion or change of copies, especially against ransomware.
