Incremental backup: safe for frequent adjustments

The secure, legally compliant retention and storage of information is subject to increasingly strict regulations. A regular backup of relevant data is therefore also essential. In addition, losses can lead to financial and time losses. To find the perfect solution for your business, we present incremental backup as one such solution and compare it with other data backup methods.

What exactly is an incremental backup?

Incremental backup is a data backup method in which changed data is saved in relation to the last full backup, but as separate units. So, if incremental backup is performed, it means that, for example, a full backup is performed on Sunday, with all data as well as software and/or the current state of the operating system being fully backed up once. If there are changes to the data on Monday, – for example, if customers change their master data, such as bank details or home addresses, or if orders are received, these are backed up separately. If changes occur again during the following weekdays that need to be saved directly, they are saved in the same way on new storage media, i.e. in relation to the previous weekday. At the end of the week, you would have a complete backup of the previous week and, for example, 5 tapes that would be needed to restore the system in the event of an accident.

Incremental data backup is particularly useful if you have to make frequent data changes in your company, if many transactions take place or orders are received that you would like to have backed up directly and if you are anxious to use as little storage space as possible. The disadvantage, however, is that all of the week's tapes and the last full backup are required to restore the system.

Distinction to other types of backup

.

An other way to back up your data regularly would be to perform a separate full backup every day, i.e. to back up your complete system including all existing data every day. The entirety of the backed up data would then be in the same location, which would greatly simplify system recovery in the event of a disaster as well as handling. However, a multiple of the storage capacity is required, which would be necessary for an incremental backup.

Another data backup method is the differential backup. This is a backup that, related to the above example, backups all new and changed data every day, saving the previous days until the last complete backup. In an emergency only 2 tapes, the last complete backup and the „Friday tape” would be necessary to restore. Whether to backup incrementally or differentially depends on how much storage capacity you have available and how much effort you can and want to devote to the restore.

An also used system is the so-called father-father-son principle. For example, all data is backed up completely on a monthly basis. This backup would therefore be understood as a “grandfather”backup. Another full backup cycle is created weekly, so in addition to the one-time monthly backup, 4 weekly backups are created, the “father”backups. The “son”-files are backed up daily, either as a full backup or incrementally. So every day either all data or the changes regarding the “father”-file are saved. If son- or father-files get lost, there would still be the grandfather-file left to allow a recovery.

To create an incremental backup on Windows 10 or Windows 7, Langmeier offers several tools. Open as well as hidden images can be mounted as drives even without system repair after restore, which simplifies backup and makes configuration and browsing easier. Browser bookmarks and Outlook mailboxes can also be easily backed up using the latest software, Langmeier Backup 9.1. The backup can be started automatically and it only takes a few clicks to save your data using an incremental backup, but also differentially or in a full backup as desired. The connection to business applications is possible via VB-Script and also alternative storage media are no problem.

Thanks to central backup protocols, 256 bit encryption and the possibility to backup to ZIP archives, data backup is made easy. Under Windows 10, an incremental backup is created quickly and easily with the help of Langmeier.

 

Incremental data backup: application areas and suitable storage media

.

Incremental backups are particularly suitable for companies whose work is based on constant data changes. Incoming and outgoing invoices, purchase orders and changes to customer, employee and supplier data, the loss of which would have negative consequences, are examples of such information. Particularly sensitive data, which increases the company's attractiveness to hackers and thus the likelihood of being compromised by malware and espionage, should also be saved and stored securely at short intervals. To ensure safekeeping, the storage media must be kept separate from the original files and protected from external influences. For example, bank lockers or specially designated rooms are suitable for this purpose. Since an incremental backup for recovery requires both the last complete backup and subsequent individual backups, the storage must be regulated accordingly.

.

If you want to perform an incremental backup, various storage media are available. Either external hard drives or specially secured and encrypted sticks can be used. There is also the option of backing up your data to network storage. However, even a NAS (Network Attached Storage) can be damaged due to power outages, floods or fires, even if it has been backed up using RAID mirroring. Similarly, backup storage on magnetic tape. These are susceptible to electromagnetic stress and their storage capacity decreases as magnetization decreases, requiring data to be restored after 5-6 years.
