Did you know that there are several types of backups for companies? Currently i do Backups It can be a matter of life and death for many institutions, since there is data, documents and files that need frequent checking.
Loss of important information such as inventories, databases or accounting can mean a major stop in company activity that you cannot afford. Therefore, It is vitally important to know and select well among the different types of support for.
What types of business backups are there?
The types of support for They differ fundamentally by the way they copy the data, the speed at which they do it and the space requirements. Among the main ones are the following.
1. Complete
A support for o Full Backup makes a copy of all selected files. Running subsequent copies again makes another backup of those files.
Restoring a full backup is pretty quick, even though each execution is slow and takes up more space in connection with other types. It is also known as full Copy.
A support for or incremental backup makes a full copy of the data and then only stores the information changed since the last copy.
Its main benefits are that it does not take long to do it and that it does not take up much space; despite this, the information retrieval procedure is more expensive.
A support for o differential backup makes a copy of all changes made since the last full backup.
It is significantly faster and requires less storage space than a full copy, but more than an incremental.
Restorations are slower than with a support for full, but faster than incrementals.
A support for or mirror backup is very equivalent to full, but it has a big difference …
Being a true reflection of the source, a file that was originally deleted will also be deleted in the backup. Therefore, should be used with great caution.
A support for o Synthetic backup rebuilds the image from a full backup using all incremental or differential backups.
Can be stored on tapes at off-site locations, with the advantage that restoration time is reduced.
Another of the existing backup types is the reverse. It is support for is an incremental backup of changes made between two instances of a mirror copy.
After the initial full copy, each subsequent copy applies the changes to the previous full copy, creating a new synthetic copy each time, going back to previous versions.
7. Continuous data protection
A support for o Continuous Data Protection Copy enables higher number of restore points compared to previous types.
Difference between differential and incremental copy:
The main difference between these two types of support for is in the amount of information to copy.
Performing two differential backups in a short period of time without making any modifications results in the same data in both backups, since it is based on the last full copy.
At the same time, if two are made Backups incremental in the same period and under the same conditions, in the second backup there will be no visible information.
Thus, differential backups ensure that only the last full copy and the last copy of this class are needed to obtain the information to restore, Meanwhile in Backups incremental, you must restore the last full copy and all incremental copies made to get the latest data.
How to select between types of support for:
Choose one of the types of support for depends on the type of company. A) Yes, if it is an SME, full backups are very useful since they do not require a lot of time and space to make them and all the information is always safe.
If it is a company that makes copies daily, a full Copy weekly combined with a copy integral everyday can be a great choice because you don't need a lot of time or space, and the information will be safe. Despite this, the problem is that an update can be lost and recovering it is slower when having to go to different copies.
In some cases it is advisable to make a complete weekly copy and a daily spread., since the data will be protected and restoring it will be fast. Despite this, the cost of storage will be somewhat higher.
