The best practices for ransomware backup include a 3-2-1 backup strategy—three copies of your data, stored in two different mediums, and one off-site backup. Veeam's ransomware backup and recovery software supports this approach, offering multi-layered protection for your data.
What is backup strategy?
Keeping at least three copies of your data is typically enough to recover from any failure scenario, keep data recovery objectives optimal, and avoid a single point of failure.
What is the best backup for ransomware?
As a quick refresher, RTO stands for Recovery Time Objective and is a measure of how quickly after an outage an application must be available again. RPO, or Recovery Point Objective, refers to how much data loss your application can tolerate.
How many backups should I keep?
What is an immutable backup? An immutable backup is a backup file that can't be altered in any way. An immutable backup should be unchangeable and able to deploy to production servers immediately in case of ransomware attacks or other data loss.
What is RTO vs RPO?
You may have heard of the 3-2-1 backup strategy. It means having at least three copies of your data, two local (on-site) but on different media (read: devices), and at least one copy off-site. We'll use “socialsecurity. jpg” as an example for this scenario.
What is immutable backup?
On the topic of the 3-2-1 rule (3 copies of data, on 2 different types of media, 1 off-site): Do you have a second full copy of your data on site, or do you consider RAID with redundancy good enough to satisfy the '2' part of the rule?

What is the rule for the sequence 1 6 1-3-1 2 2 3?
Rebounds: The 1-3-1 zone defense is notably weak when it comes to rebounding. Focusing on bringing the ball to the baseline collapses the strategy's structure; strong and effective passing takes advantage of the remodeling by creating gaps from which to score. Learn about different rebounding drills.

Full backup definition
A full backup is the process of creating one or more copies of all organizational data files in a single backup operation to protect them. Before the full backup process, a data protection specialist such as a backup administrator designates the files to be duplicated — or all files are copied.

Saving your data to an external hard drive is a good option for backing up your data and keeping it safe. An external hard drive is a portable storage device that can be connected to your computer via USB or another interface and stores large amounts of data.
Do I need to keep all backups?
Since RTO and RPO are not directly related, RPO does not need to be less than RTO or vice-versa – you could have an RTO of 24 hours and an RPO of one hour, or an RTO of two hours and an RPO of 12 hours. For example, an e-commerce site may need to be online 4 hours after a disruption, so RTO is four hours.
Do I really need backups?
Now, no mathematical formulae exist to compute RTO/RPO values. They are strictly numeric time values. For example, an RTO for a fairly critical server might be one hour, whereas the RPO for less-than-critical data transaction files might be 24 hours, and might also support the use of backup tape storage equipment.
What is the safest place to backup your data?
To more concisely define the difference: RPO is the time from the last data backup until an incident occurred [that may have caused data loss] and RTO is the time that you set to recover the lost data.
Can RTO be longer than RPO?
Veeam Backup & Replication allows you to prohibit the deletion of data from backup repositories by making that data temporarily immutable. It is done for increased security: immutability protects your data against loss as a result of attacks, malware activity or any other injurious actions.
How do you calculate RTO and RPO?
Unlike traditional backups, you don't need to worry about immutable files being jeopardized. Immutable storage guarantees the information is safe and sound.
