What are the most important considerations for backing up data?

I strongly believe that frequent backups of data can help prevent data loss and ransom ware attacks. Obviously automating this process is key. If you are very concerned about the availability of your data, then frequent automated back ups are simply essential.

Data backup solution, consider the following factors: Storage capacity: Ensure the backup solution can accommodate the amount of data. Backup frequency: Determine how often you need to back up your data. Storage type: Choose between local storage, cloud storage, or a hybrid solution

When considering backup data frequency, it is crucial to assess the value and criticality of the data being backuped. High-value data that is constantly chamging, such as financial records or customer information, may require more frequent backups to minimize potential data loss. Another important consideration for backup data frequency is the impact of data loss on operations. Businesses that rely heavily on data for day-to-day operations may need to backup their data morr frequently to ensure minimal disruption in case of data loss event.

Dependant on the data set size and sensitivity, it’s hard to recommend anything else other than daily backups. The value of having of having an easily comparable daily snapshot in case of total system failure is something money can’t buy.

Back up frequency just refers to how often or frequent you need your data to be backed up. This may differ depending on how sensitive the data is and how often the data is modified or tampered with. There is also the option to set your device to perform backups automatically depending on the interval you want to give it.

Ideally you would want to do at least a 3-2-1 approach in backing up your data; three copies of your data, with two being local or on-site and one being off-site in a secure location. However, with the rise of ransomware attacks, many are now suggesting a 3-2-1-1-0 or 4-3-2 solution in backing up your data. The 3-2-1-1-0 is similar to the 3-2-1 approach, but adds another copy of the data that is kept offline or airgapped and that there are zero errors across all backups. The 4-3-2 approach is similar to the 3-2-1 approach as well, with the main difference being there are 4 copies of the data and it is backed up be in three locations, two of them being off-site.

Depending on what type of data you’re planning on backing up, you should be able to choose its location. Every back up location may have its positives as well as its negatives so it’s best to pick the one that best favors whatever data you’re trying to back up.

The backup serves as the ultimate safeguard in the face of a disaster, necessitating secure off-site storage to guarantee its accessibility when needed. This location should be easily accessible at all times and fortified for added security. Common approaches to achieve this include utilizing cloud-based backups, renting a secure bank safe deposit box, or engaging services from specialized companies.

Flash drives are suitable for transferring data and NOT for storing data. Personally I recommend 2 ways of storing backups. 1) HDD: My main storage for backups. Newly purchased hard drives with 0 power cycles and power-on counts. They are sturdy, robust and cheap. Due to the fact that hard drives use physical means of storage, in the worst case scenario there are high chances that you can recover your data. 2) Cloud: No hardware needed from your end whatsoever. There are many providers for cloud storage. Worst case, vendor's servers are destroyed or burnt to the ground, which is near to 0%.

Le format de la sauvegarde est très important a cause de la compatibilité pour l'accéder. Il y a des programmes que s'on réinstalle le système on perde les donnés sauvegardés, et ?a c'est pas utile. Faut bien les protéger mais qu'on puisse avoir accès quand on à besoin

A combination of full and incremential/differential is best on my opinion. And based on need full back each week/month and diffs daily

Must be up to date (media should be available and reliable) preferably solid state drives. It also should be done from a main computer either from IT or a portable computer. Trying to standardize the media is difficult but should be the aim.

Backup data format varies based on factors such as data type, storage capacity and data importance. Common formats include Incremental Backup (capturing changes since the last backup), Full Backup (comprehensive standalone copy of all data), Cloud Backup (offsite storage in compressed, encrypted formats), Snapshot Backup (captures system/data state for point-in-time recovery) and Custom Formats for critical systems (precise recovery and versioning).

Encrypting your backed up data is important. This helps keep the data secure and original. You never know where your backed up data is going to end up so it’s very important to take that step to encrypt that data to make sure that no unauthorized person is going to be able to access your data. It doesn’t end at encrypting the data. After encrypting the data, you need to make sure that the keys to decrypt the data are kept and kept safe.

Es importante mantener un buen cifrado de los respaldos para que los mismos en caso de tener una brecha de seguridad estos no sean fácil de acceder y no sean vulnerados.

When stored in a physical locked on site location, encryption is less important. In cloud, encryption is a must. When using a serious partner, good encryption should be a part of the solution

Of course, encryption helps when we are talking about safe practices of data security. In case you keep your backup on a computer that is not connected to the internet and you are the only one that has access, then you can disregard the encryption step. However, it is good to encrypt your backups just to be on the safe side.

Verify backup data by regularly performing test restores, ensuring data integrity, comparing checksums and validating backups against the original data. Regularly review backup logs, conduct random file checks and simulate recovery scenarios to confirm the reliability and completeness of the backup.

Having a backup that cannot be restored when needed renders it useless and without value. Therefore, it is essential to verify the backup using the right tools. Additionally, regular backup testing is necessary to ensure that the restoration process occurs smoothly without any issues.

You should charge the way you think of backup in general. You should not design a backup-solution, but rather a restore-solution. So when you design the solution you must have in mind that it should be easily restored. Check both single file restore and vm’s etc. file restore could be verified monthly, vm’ yearly

Ficar atento as mensagens de logs/erros do próprio programa Abrir o próprio arquivo que foi copiado para ter certeza que n?o deu problema Se for copia de sistema operacional precisa de outro computador com as configura??es mais parecida possível e tentar fazer uma restaura??o

It is important to perform frequent backup restoration test exercises. Having the data available and unmodified is one side of business continuity health, but another is the consistent availability of data. Regular backup restoration tests insure that when restoration is necessary, technical hurdles have already been addressed and do not delay restoration, or negatively affect the bottom line due to a prolonged service outage.

Don't be afraid to have multiple back ups on different locations. Since depending on how bad given a situation that could cause data loss it's always better to know you have multiple backups. Having one single point of failure which in this case could be having only one backup will certainly cause data to be inaccessible.

Always keep your backup in at least 2 different locations. When making a backup there is a high chance that the host may be unreachable. A dead drive, a computer that doesn't boot. Better be safe than sorry.

Have a plan test after the back up completes and if discrepancy found trace it fix it. Try till your back up comparison to data been backup is a 100% same as the original data. Then implement the Backup frequency. Also create a fall back archived data.

Always follow the 3-2-1 method of backing up your data. You need 3 individual copies of your data. 2 of those copies should be readily accessible on two different devices. 1 of those copies should be off-site in a safe location (friends house, safe deposit box, cloud storage). This covers your bases across a variety of scenarios including drive failures, fires, theft etc.
