Backup software is designed to backup all types of storage and computing devices to disk, tape or the cloud. Backup is a chore but is essential in protecting the business against increasing threats that paralyse a business such as ransomware. The software comes in a variety of guises including protection for operating systems Windows, Linux, Apple, Unix, OS/400…, applications including Office 365, Exchange, SQL, Oracle SAP…, storage devices RAID, NAS, Unified, Flash… and mobile computing tablets, phones and notebooks.
Backup software choices
Whilst there are different types of backup software available, deciding where your backup data resides also plays a critical part on how soon you can recover from data loss or system failure. Traditional backup relied on tape, increasingly disk started to provide disk-2-disk systems, they then including compression and deduplication and now we have backup to the cloud. The software has also evolved to include deduplication, replication, archiving and backup to the software vendors own cloud. Companies tend to change operating systems more than they change their backup systems and software!
Increasingly industry is being instructed to have in place adequate data protection systems in place to protect against data loss and secure companies information. With stricter fines and penalties in place those that flout the laws. With increased fines and legal penalties in addition to the loss of service, data and customer good will data loss of any kind can cause all types of industries irreparable damage. Legislation such as Sarbanes-Oxley Act for example, cover strict data sovereignty and security requirements prevent organisations from saving personal data to the cloud if that data leaves the country of residence at any time.
In today’s connected world, it is no longer acceptable to backup once a night. As stated on this site data volumes are increasing 1-2x per year and the 8-hour backup window no longer exists. A backup today should be an application that runs continuously throughout the day and alerts you of any issues so that you rectify the problem before it becomes a headache. It should also be able to backup at the block level rather than a file as this will greatly increase backup performance and allow for only changed blocks to be backed up.
Critical to any business is the ability to recover data from corruption, loss, attack or environmental disaster.
- RTO Future (Recovery Time Objective) – Quite simply how quickly a business can recover from the above within a given service level i.e. loss of a server = 2 hours to be functional
- RPO Past (Recovery Point Objective) – How far back your business is prepared to lose data based on the backup routine i.e. restore last nights data = 8 hours lost transactions
Any DR plan is only as good as the last restore. If you install new systems and decide to run a DR plan 3 months later then the chances of hitting an issue are high, alternatively, if you perform a weekly restore of random data, monthly restore of a disk and quarterly restore of a server then the chances of having problems should a real disaster strike are massively reduced. There is no substitute for planning and documenting your procedure in detail as without one you are steering a rudderless ship in a stormy sea.
