An effective backup strategy: a bulwark against the loss of your data
There are many incidents that can cause your data to be lost, but hardware failures or other failures, human error and cyberattacks are the most common.
These incidents can happen at any time, and usually it happens when it’s not the time…
As it is impossible to predict when a disaster will happen, the best thing is to prepare to implement the right technologies and carry out the best practices.
“Each backup strategy is unique, but it must be defined with care and precision. Having a backup strategy adapted to your needs is the first rampart to deal with the threats that surround us.”
The objective is to know the type and volume of data available in order to determine what must be backed up. This is where we can ask ourselves the question of the value of data, given that not all data is created equal. It is therefore a question of identifying the most sensitive data, the loss of which could strongly affect the operation of your business.
The idea is to define the frequency at which backups must be made, which can be daily, weekly, monthly. Consideration should be given to how often your data is refreshed to limit the time between the incident causing data loss and the most recent date of recorded data. It will also be necessary to take into account future projects that will have an impact on the volume of your data.
The backup strategy depends on the size of your backup window, which is the period during which you perform backup operations with system downtime for users.
When defining a backup strategy, you should choose a backup window that works for everyone and has the least impact on production.
When addressing the issue of retention, one must ask how many years the data should be kept. This is where the notions of archiving (for “cold” data) and backup (for “hot” data, which must be available for fast restores) will come into play.
It is a question of defining where you wish to redundant your data: on site? with local replications (multiple copies) or multi-site replications? on the cloud?
A suitable backup strategy must make it possible to guard against attacks (internal or external), such as malware, ransomware, cryptolocker. It is therefore always necessary to ask whether the data must be encrypted, and especially who can access the backups?
