The topic of backup is important not only for beginners, but also for experienced users in this field. Why do we need to backup the site and what types of backup exist?

Backup solutions

Backup – create a copy of files and folders on additional storage media. Backup is done for data recovery in case the information is damaged or collapsed in the main storage location. Backing up is especially important if you have your own website hosted by your hosting provider. Backup serves as a kind of lifeline, in case of loss of important data.

What are the reasons why important data may be lost:

Server / computer crash Trust in a single device that stores information, in any case not necessary. With each can happen force majeure, because of which you can lose very important data, especially sad when they are stored in one copy.

Program failure

Because of such problems, important information may be deleted or damaged, which cannot be restored if there is no backup.

Intruders can specifically damage your data or steal it for later use. This is often done with the help of malicious programs that infect files, and fraudsters require a ransom to restore them. Antivirus in such cases is often powerless.

The user himself

Due to inexperience or haste, you may accidentally damage important documents / files for you. In such a case is useful backup, which will restore the lost data.

Full back up generally generally concerns the entire system and files completely. It can be held weekly, monthly or quarterly. Such a backup implies a complete copy of the original, regardless of the time and its changes. This method is the most reliable, although it is time consuming and takes longer than other types of backup. This type of backup is best performed at the weekend, when the load on the site is minimal. Full backup also requires large data storage. What are the advantages of this method: the ability to restore the system or the required fragment from almost zero in full. Keep your faith over the Best Cloud Solutions Company In Singapore in this process.

Differential backup — when using this backup method, every file that has been changed since the last full backup is copied again each time. This method greatly speeds up the recovery process. After all, you just need the latest full and last differential backup. This method is quite popular, because copies of files are made at certain points in time, and this is especially important in case of infection of the site with viruses. This copying can be done, for example, with the help of a special utility rdiff-backup. Differential backup saves only the information that has been changed since the previous full backup. This not only saves your time, but the disk space for storing such backups.

Incremental backup (Incremental backup) – involves copying only those files that have been changed since the last time you perform a full or incremental backup. This means that the next incremental backup adds only files that have been modified since the previous incremental backup. However, the data recovery process itself takes more time, because it is necessary to restore the data of the last full backup, in addition, the data of all subsequent backups. At the same time, changed or new files do not replace old ones, but are added to the media separately.

Backup by cloning – allows you to copy an entire partition or medium (device) with all files and directories to another partition or to another medium. If the partition is bootable, then the cloned partition will also be bootable.

Image backup is an exact copy of the entire partition or media (device) that is stored in one file. Backing up in real time allows you to create copies of data directories without rebooting.

Users often do not think about the need and importance of backup when it comes to recovering lost data. In 2015, an article was written about the most stupid user mistakes about backups (“ 11 Stupid Backup Strategies ”). So what kind of errors most often occur when it comes to backups?

The first and in fact the most significant mistake is the absence of backups . If you do not make backups at all and hope that everything will be all right, then sooner or later your data may not only suffer, but also be completely lost. Since the reasons for this are very different and I considered them at the beginning of the article.

Relying on data recovery services? There are special applications that allow you to recover lost information. But this option is suitable if you accidentally deleted a file and want to return it, and in the case of, for example, a fire or data theft, this method, alas, will not work.

No need to hope for autosave . In certain applications, there is an autosave feature. Quite often there are situations when users accidentally delete autosave files. Everyone knows that most backup systems assume that the user will at least save and name the file – after all, autosave is often turned on after this step.

You can not store all backups in one place on the same machine . If a meteorite falls on your home, you will lose all the backups that you have stored. But what is the probability that the same meteorite will fall on a data center in another city at the same time. Therefore, it is better to store backups remotely and if the data is very important, then in several places.

Programs for monitoring the operation of hard drives.More in the next article.

Only on-line backups? It is very important to have backup copies not only in cloud storages, but also on ordinary hard drives. After all, there are cases when the Internet may be absent or be very slow, and a copy of the data is needed right here and now. Then you will undoubtedly be useful to backup on a separate media, which can be used anytime.

Your web applications also need backups . Many of us use apps like Google Docs every day. But from time to time there are situations when important documents from the repository can disappear without the possibility of recovery. Therefore, if you store valuable information in such applications, it should also be backed up to a separate data store.

RAID and backup are not synonymous . About what RAID and their types , I wrote earlier. Therefore, please note that if you accidentally delete a file, it will be removed from both mirrored RAID drives. If a directory or file was damaged, a virus has penetrated to you, then it will equally affect both drives. If the array is stolen or damaged, the files will be completely lost. RAID protects your information only in case of failure of one of the hard drives. And a disk array is in no way a synonym for the word “backup”, which in any of the above cases will help to restore important information.

All types and methods of backup allow you to do the most important thing: to protect you from data loss and your site as a whole in case of force majeure situations. Please note that on our hosting rates , we do regular backups, and on VPS rates, you are responsible for backing up your information.
