In that case we would engage cloud support for recovery and should do: - validation to data integrity, - validate backup schedules to avoid backups during data writing. - periodic backup restoration testing

Reactive actions: 1.Effective data recovery tools may help in case of hardware storage issues. 2.In case of ransomeware attacks you need to take obvious step if data is business critical. Preventive Measures: 1.Based on RPO, backup size and storage capacity you can plan multiple backups in a day. 2.Keeping backups copies in multiple cloud environments is an effective hedge. 3.Having a copy on-prem and periodic restoration and data sanity checks has to be baseline. 4.Measures to ensure robustness against cyber attacks: sort of off-site/ cross location/ tape backups etc., and technologies like air-gap mechanism, encrypted backups etc would help. 5. Backup automation tools make the ops easy helps to avoid manual mistakes.

Here is the systematic approach to effectively recover your data: 1. Identify the root cause: this could be hardware issue, network connectivity or human error 2. secondary backup options: ensure that the cloud backup is up to date and if you have a local backup system check if it can be recovered. 3. Explore DR site backup

Checksum verification: For each piece of data, generate a checksum using a reliable algorithm. Many file management tools and backup software automatically compute checksums during data storage. ... Hashing verification: Similar to checksums, generate cryptographic hashes (MD5, SHA-256, etc.)

Para restaurar los datos de manera efectiva, se pueden tomar varias acciones clave: 1. Verificación de conectividad de la infraestructura de backups a la infraestructura virtual donde se quiere restaurar. Verificar cambio de credenciales de la cuenta de backups, bloqueo de cuenta, expirado de contrase?a, verificaciones de networking como rutas, permisos de firewall, y mecanismos de seguridad más sofisticados que pudieran bloquear el anti DDOS 2. Si todo lo anterior falla, verificar el estado de las copias de seguridad: Si el fallo es reciente, revisa el estado de las copias de seguridad anteriores en la nube o localmente. Puedes restaurar los datos de la última copia exitosa.
