Backup concept: how to back up your data properly.

Anyone who processes data must always have a current data backup on hand. This way you can quickly restore your data in case of loss.Whoever works with data must always have a current backup of his data. This is the only way to restore everything in case of a loss.

Before you backup, should know what data you want to back up, where and how often. There are more things to a professional backup concept. Learn worth knowing about this in this article.

.

The backup target

.

First decide where you want to backup the data to, that is, what kind of backup media you want to use. It is recommended that you read our blog article on this. This can help you decide which backup medium best meets your needs.

.

Backup and Restore

.

If you want to back up data often, then using an external hard drive is the easiest way to do it. With an external hard drive, you have virtually zero hassle when performing a backup: connect the hard drive, perform the backup. In addition, if you have a permanently connected hard disk, you can have data backups performed automatically. You need to write to a CD or DVD and store it in a good place so you will find it again. A CD is easily lost. This is important because you cannot restore a system without the backup on a disk.

.

Some customers have set up the backup program so that the employee inserts a USB drive, the backup then backs up all the data. Then all that's needed is an internal company directive that all employees must plug in the USB stick once a day, and that's it.

Personally, I have the backup set up so that I can plug in a USB hard drive named "Backup", then the backup of my data automatically starts to that drive. Then I put the disk back and take it home.

Data can also be backed up over a local network or VPN network to a NAS, a storage server, or even to another computer. To do this, you can use UNC paths for source and destination respectively in the form \\Server\ShareName . As a special feature, you can also back up to FTP servers.

.

Devices like tape drives and streamers are supported by Langmeier Backup as well .

The Generational Principle

.

What do you do when a colleague comes in and says, "I need a backup from the day before yesterday!". Yesterday, and today at noon, a backup was also already made, but the colleague needs one from the day before yesterday. Don't forget to think about that when you set up the backup! This case can happen, and that is why it is not enough to set up a daily backup, each time overwriting the previous day's backup.

.

In practice, however, not all file types and not all directories require the possibility of such a historical restore. If there are only files in a directory that are created once, never changed again, then a backup in the generation principle is not really necessary. That is why Langmeier Backup has built in a simple option that can be considered as a replacement for the generation principle. Especially smaller companies, as well as private individuals, like to use this function, because creating a "real" generation principle backup would be much too complicated for them. In Langmeier Backup, all directories and file types that are to be backed up historically must be entered - the backup then does the same so that earlier versions of these files can be restored.

.

If you want to apply a proper generation principle, as you learned in IT school, you need to know that you can use different directories for the backup, but better use different disks for the backup. For example, you can then put disk 1 on Monday, disk 2 on Tuesday, and so on. On Friday, a backup is made that is kept for four weeks, and at the end of the month, a backup is made to a disk that is not touched again for a year. The next week, Monday's disk 1 is overwritten again. In four weeks, the first Friday backup is overwritten again. In a year, the first month's backup is overwritten again.

Backup types

.

Incremental backup

.

By default, Langmeier Backup runs in incremental backup mode. This means that all files are backed up first, but then only the changed or newly added data is backed up. Accordingly, to use incremental backup mode, you don't need to set anything.

.

Full backup

.

If you want to do a full backup, that means all files should be backed up completely, you have to uncheck "Backup changed files only" in the job.

Differential Backup

.

For a differential backup, use multiple backup disks. On the first disk, you first make a full backup. The next day, however, you back up to the next volume only those files that have changed since the last full backup. On the second day, you repeat this procedure and back up all files that have changed since the last full backup. You repeat this differential backup as often as it suits you. You can easily set this up in Langmeier Backup: define two backup jobs. Define the first job as a full backup by unchecking "Back up changed files only". Define the other job so that only the changed files are backed up. In addition, for the latter job, make the setting "Do not reset archive bit."

.

Delete disk before backup, or format it?

.

If you want to format a disk before the backup, for example before the full backup, create a batch file that does this. Then include that batch file as a script to run before the backup. Since the format function is somewhat rigorous, I didn't just put a check mark in the program. Only those who know what they are doing should do this. For the others there is still the setting "Delete CD/DVD or destination directory". Here every directory, in which files are saved, is deleted first.

Creating a professional backup concept

.

If you want to use a professional backup concept, then this requires some planning. Therefore, write down the main points of your backup concept and inform your employees what needs to be done. Designate a backup manager in the company, and a deputy. Define the following points:

.

- The backup is to be kept off-site (don't forget encryption; someone could steal the data along the way!): who takes the backup where?

- the backup needs to be checked regularly: who takes it and how often?

- Backup and Restore: A restore should be simulated once in a while.

.

- Data shall be backed up at least once daily.

-In smaller companies, the boss often takes the backup home daily. In larger companies, this task is often outsourced, or the backups are stored in specially secured basements and bunkers.

.

Conclusion: as you can see, old school professional data backup is not that easy. But, that's why I included a simple mode in Langmeier Backup because a good data security is achieved in Langmeier Backup even if you leave everything at the default settings, and simply alternate between two to three backup media. If possible, turn on historization for selected file types, and you're good to go. This is much easier than doing old-school professional backups. However, both are supported, of course, so professionals can do something with the program.

How often do you back up your data?

.

One part of your backup concept is to be clear about how often you want to back up data. Many users want to be in control of this themselves and only back up when they feel it is appropriate. Other users would rather not think about the backup at all, and leave this task to the automatic function available in the backup program. Both ways are correct and sensible. Langmeier Backup offers a wide range of automatic backup options. Likewise, multiple jobs can also be set up at different times and in different cycles.
