Creating a Backup<\/span><\/h2>\n\n\n\nAccording to the Infrascale, 67.7% businesses experienced significant data loss till February 2025.<\/a> This number is pretty alarming, but the threat goes even further:<\/p>\n\n\n\n\n- About 40% of companies lost critical data due to a cyberattack in 2025<\/a><\/li>\n\n\n\n
- Attacks on cloud services increased 26% in 2024<\/a>, which raises the need of looking for a more reliable data storage solution (in-house for the maximum control)<\/li>\n\n\n\n
- Two out of three security leaders see AI-powered attacks as inevitable in 2026 (about 69% of the experts), yet only 40% report full preparation for this threat.<\/a><\/li>\n<\/ul>\n\n\n\n
Most businesses are inextricably linked with technology and each other, so the failure of one could easily create a knock-on effect that affects many more businesses.<\/span><\/p>\n\n\n\nYou may wonder, what are the main causes of data loss? Here\u2019s a list of the most significant Open-E solutions to avoid them:<\/span><\/p>\n\n\n\n![\"Mistakes](\"https:\/\/www.open-e.com\/blog\/wp-content\/uploads\/2024\/03\/Mistakes_in_Backup_infographic_new-1720x2048.jpg\")

Of course, these situations may occur while using a backup as well. However, if you use the correctly set up configuration, you can avoid most of these problems.<\/span><\/p>\n\n\n\nCheck if Everything Works Well<\/span><\/h2>\n\n\n\nCreating a backup is a significant step in the right direction for any company<\/strong> that requires a highly responsible approach. It leads to many positive outcomes, but only if done correctly. Let\u2019s look at the main aspects that should be considered regarding this.<\/p>\n\n\n\nKeeping up with Backups<\/span><\/h3>\n\n\n\nThere are various configurations available for any data storage solution connected to backup servers, but setting the correct one up can quickly become complicated. And even if a backup was set up correctly, it <\/span>can\u2019t provide us with a 100% guarantee that nothing will happen to the data over time<\/b>.<\/span><\/p>\n\n\n\nYou\u2019ve probably heard that the movie <\/span>Toy Story 2 by Pixar might have never been released<\/span><\/a> due to data loss caused by human error – one of the most common reasons for data loss, as we\u2019ve already shown above. Yet this arguably wasn\u2019t even the worst part of this story. The redundant data kept by Pixar on the backup server wasn\u2019t continuously checked, and the data was not backed up for a whole month, which may even be considered worse than someone accidentally deleting the movie. In any case, we can consider this a lesson learned.<\/span> One of the worst things that can be done with backup is to create one that is never verified again.<\/b><\/p>\n\n\n\nLooking into Retention Plans<\/span><\/h3>\n\n\n\nFirst, let\u2019s start with a description of a <\/span>retention plan<\/span><\/a>. At Open-E, we describe a retention plan as follows:<\/span> a retention plan is a process of automatically creating and deleting <\/b>snapshots<\/b><\/a> at a frequency that the user sets<\/b>. This can be done on any source a user chooses. It can even be done with backup copies, typically located on the local or remote backup server, perhaps even both. A retention plan combines several rules, such as the intervals at which the snapshots are made and their retention periods, i.e., how long the snapshots should be kept on the main node and, optionally, on a second node as well (Off-site). <\/span><\/p>\n\n\n\nIt\u2019s essential to mention that a<\/span> snapshot is not a backup itself<\/b>. However, it can be used as one. When a snapshot is copied onto the backup server, it can be used to recreate the data on the snapshot by transforming it into a clone. Snapshots function this way to better protect against data loss or corruption, including ransomware. Since snapshots are made in a read-only format, they cannot be encrypted.<\/span><\/p>\n\n\n\nDuring the configuration stage, deciding which retention plan is most suitable for your company\u2019s needs is essential. For instance, <\/span>you can take snapshots every five minutes or once a week\u2014it\u2019s up to you<\/b>. But sometimes, these configuration settings can be set up incorrectly. <\/span><\/p>\n\n\n\n![\"animated](\"https:\/\/www.open-e.com\/blog\/wp-content\/uploads\/ezgif.com-video-to-gif-converter.gif\")
<\/figure><\/div>\n\n\nFor example, let\u2019s say you work in an organization where business-critical data constantly changes throughout the workday. However, the backup is created only once a day to avoid overloading the system. Due to that, most of the business-critical data created during a workday may be lost if a problem occurs towards the end of said workday but before the daily backup. Using Open-E JovianDSS\u2019 retention plans, you can record the state of the volume as often as needed, without any waste of time or significant risk of overloading your system.<\/span><\/p>\n\n\n\nReal-life Use Case of Misconfigured Retention Plan<\/span><\/h3>\n\n\n\nNot a long time ago, one of our clients requested our support as all the snapshots that they kept as backups at an off-site location disappeared. When our team looked into the problem, it appeared that the retention plan was set incorrectly. The client had set the off-site retention plan for a much shorter time than was required and the older data they wanted to reach was erased. This is why you should ask yourself the question, \u201cHow long should I keep the backup copies\u201d? The answer may vary, depending on the exact type of documents ( e.g., tax documents when working in the government sector compared to say, discount flyers, for a local business) you\u2019re storing.<\/span><\/p>\n\n\n\nTo avoid such unpleasant surprises, we suggest double-checking the retention plan of your data storage solution or requesting technical support at the time of installation.<\/b><\/p>\n\n\n\nSpace Matters<\/span><\/h3>\n\n\n\nIt\u2019s essential to evaluate the needs of your enterprise correctly; needs like how often a backup should be made, how long it should be kept (the retention plan we described above), and how much space it can occupy on the backup server. Moreover, you also have to estimate the amount of data that the company can reasonably accept to lose after a potential disaster and how much time a company can take to recover data before it starts to harm the organization’s work processes. These can be calculated using the following metrics:<\/span><\/p>\n\n\n\n\n- RPO (Recovery Point Objective)<\/strong> \u2013 the maximum acceptable amount of data that can be lost after the recovery.<\/li>\n\n\n\n
- RTO (Recovery Time Objective)<\/strong> \u2013 the maximum acceptable time a system can be down after unexpected failure.<\/li>\n<\/ul>\n\n\n\n
Using these, you can decide what best matches your company\u2019s goals even before setting up the data storage solution and backup server. It should be noted that using an off-site server as a backup may not let you recover the data as fast as required. You might also consider creating a backup on-site to accelerate the recovery process.<\/span><\/p>\n\n\n\nSo, what could happen if you underestimate the workload of your business? Some of our customers recently found out when they had to deal with a lack of backup space for their snapshots, which they used as their backup. There are several reasons why this can happen: <\/span><\/p>\n\n\n\n\n- Incorrect business workload estimation<\/strong> (when you configure less space than is needed).<\/li>\n\n\n\n
- Poor retention plan configurations<\/strong> (snapshots taken too often, sometimes even without any changes to the data, which then overloads the storage space)<\/li>\n<\/ul>\n\n\n\n
Generally speaking, overloading a server and running out of storage space isn\u2019t a big deal if you react as soon as possible. However, if you miss that moment and the system tries to take another snapshot before the situation is rectified, the snapshot will not be recorded, and the latest changes to your data will not be saved.<\/span><\/p>\n\n\n\nWith <\/span>Open-E JovianDSS<\/span><\/a>, you can always ensure your data and backup are safe.<\/span> With the <\/b>On- and Off-site Data Protection<\/b><\/a>, you can create multiple backup servers locally as well as in remote locations for extra protection. <\/b>Additionally,<\/span> with the High-Availability clustering infrastructure,<\/b> you can simultaneously run the system with almost no downtime <\/b>and eliminate any single points of failure. It gives you the peace of mind that your workload will not be interrupted as your workday proceeds.<\/span><\/p>\n\n\n\nBeyond Backup: Understanding the Data Protection<\/span><\/h2>\n\n\n\nWhen it comes to data loss, backup issues can be downright disastrous for many reasons, not only described above. E.g., <\/span>the total amount paid in ransomware attacks in 2023 surpassed $1.1 billion.<\/span><\/a> It gives you some perspective on how dangerous these attacks are. Ecept that there\u2019s also <\/span>silent data corruption, cluster rebuild and drives failures, natural disasters, human errors, system downtimes, or just thefts.<\/b> If you\u2019d like to know more, about efficient data storage protection in kind of unexpected disaster – check out the brochure <\/span>\u201cBeyond Backup: Understanding the Data Protection\u201d<\/span><\/a>.<\/p>\n\n\n\n<\/p>\n\n\n
