![]() ![]() Stored on-premise using a network attached storage (NAS).Files consume more storage space as they are not compressed.Malware infection on the network can render backup useless.Stored on Amazon AWS S3 cloud storage with "anywhere" access.Requires time and process to restore files.Files are compressed to minimize storage requirement.Can be used to recover from a malware attack (e.g., ransomware).Daily, weekly, monthly and yearly backup schedules.Can restore data from up to six years ago with the content as it was at the time it was backed up.Follows retention policy using life-cycle management.This design consists of three levels of data backup each with offering specific benefits when it comes to recovery time, retention, and accessibility. Implement a cold offsite backup using Amazon AWS S3 and Glacier could storage service with life-cycle management to retain files for the required six year retention period.Implement a warm offsite backup using Amazon AWS S3 cloud storage service.Implement an on-premise hot backup using a NAS.A 24-hour replication of file kept off-premise, in its native file format.no compression or save in a proprietary format by a backup software) A real-time replication of files kept on-premise, in its native file format (e.g.Daily and weekly backups kept for five weeks. #Data backup best practices fullFull yearly backup perform at the first of every year.Full monthly backup performed the first of every month.Full weekly backup performed on a weekend day.Incremental daily backup performed nightly.With the requirements defined, we are than able to propose a design that will meet the requirements for our small business client, their budget, and small I.T. No tape medium are to be used (too much effort to rotate and manage tapes).Minimal administrative effort to manage backups ("set it and forget it").Employees must be able to access and interact with files from a backup while at home using either a company-issued or personal computer (in the event office building is inaccessible).To be able to recover files as it was from a particular time period (Recover Point Objective - RPO) during the past six year (e.g., for audits, investigative purpose, retention, and similar scenarios).To be able to recover files from a backup within hours (RTO) if the office or network becomes inaccessible for a long period of time (e.g, power outage, earthquakes, and similar).To be able to recover files from a backup within hours (Recover Time Objective - RTO) if attacked by ransomware (and not have to pay the ransom).To define what a comprehensive backup means, as it relates to this particular project, here's a summary list of the requirements: The objective is to have the ability to effectively and quickly recovery from a disaster, as any business would. One of our projects we worked on was to design a have a comprehensive data backup strategy with a requirement to be able to restore data (several hundred gigabytes) within just a few hours. ![]()
