Acronis and comet backup are also popular tools for taking backup
Comet's backup solutions are good depending on your data volumes pricing as varies according to that and other factors. There are many other possibilities too, I can give you some possibilities if you like?
As for Acronis, don't especially if you have any confidential data (above all if it's personal data such as financial, medical or anything that would cause embarrasement)! I'll explain, I am a consultant doing vendor evaluations for the EU and other big organizations. We recently looked into several backup companies on behalf of a customer and we rapidly came to the conclusion that we weren't even going to present Acronis as a viable option as no serious IT project or purchasing manager would even consider them given our findings unless they wanted to get fired (even though it's not really Acronis' fault but all the same). There are many reasons for this and I'll go through them; if you type "Acronis hacked" into Google, you will see many many references to an incident in March this year where an Acronis customer's account got hacked and their backups published on the dark web. Acronis' explanation was that a customer's account got compromized outside of their systems (whatever that means). We did not find this explanation very convincing as the group that did the hack is a state sponsored Russian hacking group that has the stated aim of attacking all anti Russian companies and institutions. This appeared to us as a clearly targetted and successful attack. Acronis is unfortunately top of the list that Russian groups want to hack.
Many people think that Acronis is still a Russian company as it was founded by Russians (most of their staff are still Russian even though "officially" it is a Swiss / Singaporean company). Recently, the founder of the company moved aside to allow a non Russian to take over and they moved their operations out of Russia some years ago to avoid sanctions and to appear "less Russian". The founder even went to the extent of changing his name to something more "European" to sound less Russian (https://en.wikipedia.org/wiki/Serg_Bell). Bell has taken a strong anti Russian stance with Acronis even donating very large sums of money to the Ukraine. There have also been other reports in the Press such as the Washington Post about Acronis' real connections with Russia, Putin reportedly stating that "Bell is more useful to him from abroad". There is also a risk in that the company could face being banned in Western countries at some stage.
If you are a nationalist Russian hacking group with the aim of attacking "anti Russian" sentiments and actions, you can just imagine how they perceive a Russian individual and company that changes their name, moves their company, strongly criticizes Russia and then donates money to the "enemy"! We follow dark web hacking forums and Telegram accounts to see what is going on. Acronis is under constant attack and they will get in sooner or later (as they have already done), they are relentless with massive resources. When they get your data, they will keep it until it suits them to release it. There were apparently references from Russian groups about Acronis's technical center based in Bulgaria. They seemed to hint that they have insiders in there which seems credible given that Bulgaria is an old Soviet satelite.
Most people still think the company is Russian, this can cause problems with management and customers when this is brought up (
).
As I said before, all of this is not really their fault but you would be mad to take the risk when there are other excellent solutions available that don't come with the same risk (take a look at backups solutions such as VEEAM or Azure for example).
