Best practices for decentralized units and branch office backup
When implementing a backup system for remote units or departments, must be taken into account some practices to ensure a reliable system.
Best practices for a centralized backup system
Remote copy of the data
Eliminates the need for a complex system in each of the branches, thus reducing cost and maintenance site.
Centralizing backups for better use of technological resources
Centralization of data makes full use of available resources (tapes, disks, etc.), eliminating waste.
Band control, compression and incremental copies
How the data will be transmitted through a limited link (and not in an excellent gigabit network as in a local environment) the system must have an advanced bandwidth control, use compression and make incremental copies to ensure that copies are always up-to-date and that the utilization of the link to other services will not be compromised.
And consolidated management reports
Being centered, the solution allows the control of all units is a unified form, without the need to check multiple management consoles. Everything is in one place!
Security during transmission of data
The data is exchanged over the Internet or for MPLS networks, which are not 100% secure. Therefore, it is essential to use cryptographic algorithms for the copy of the data, ensuring the safety and inviolability of data while copying.
Data storage security
Data storage security, 3 points are crucial:
1) Reliability in storage: using arrays of high reliability, ensuring safety and system performance.
2) logic: logical protection systems such as firewalls and IPS eliminates the risks of attacks and security breaches.
3) data encryption: store the encrypted data ensures that in any security breach data are “unreadable” the attacker.
In cases pinpoint where restoration is lost an accurate data, such as a database, a folder or just some files, a remote restore meets the demand completely, but in cases of disaster, where a full restore is required, the restore time via link can not meet the need of the business.
For this situation there are the following options:
1) direct Restoration in the data center. For large volumes of data, it is possible to recover the data directly in the data center on which this backup, restoring the backup stored on a USB external drive and taking the copies to the unit for the restoration.
2) Restoration via “bridge.” Creates a bridge somewhere that has a good connectivity (in the array, for example), low if the backup and then he is taken to the unit for restoration.
New technologies for compression, encryption, and the continuous improvement in telecommunications infrastructure allow data to be sent remotely, quickly and safely. This wasn’t possible until recently.
Use remote and centralized solutions is currently the best option to resolve the issue of performing backups of various remote units or branches, dramatically reducing the cost of project implementation and facilitating the management of the system.
Problems in the absence of centralized backup units and branches of the company
Manage dozens, sometimes hundreds, of backup routines in several municipalities demand a lot of time and energy, causing companies waste resources (whether human or technological) or end up having an unreliable backup system, putting information security at risk.
Implement a backup system from different locations is distinct from backup data center solutions or centralized DATA CENTER. We will demonstrate what the problems are and what solutions can be adopted to ensure data integrity in this type of environment.
Difficulties, challenges, and problems
-Decentralization of data
The data is decentralized and POINT. A strategic planning or nature of the operation (a supermarket chain, for example) you must adapt and be able to guarantee the safety of data in different locations.
Even in cases where the systems are centralized, almost always there are data stored locally in the branch offices.
Remember: the data of an affiliate is as important as the data of the array.
-Different solutions in each locale
It is common to find different solutions for each of the locales, making you have to manage multiple technologies. This makes the team training and mainly undertakes the monitoring and management system of backups.
-Decentralization of the Directorate and reporting
You can’t handle multiple systems, environments, and backup routines. Even designating a person or team to this task, the complexity of managing several systems decreases considerably the success rate of backup methods and data recovery.
-Who runs the backup locally?
Units or branches, usually do not have it person, causing the exchange of tapes, or backup, maintenance is the responsibility of an ordinary contributor, that by not understanding the importance of the backup system, neglecting the exchanges of tapes, putting company data at risk.
-High cost of implementation
Each unit has to have a proper backup system, with tape drives, software and various tapes. If we multiply by a number of branches, we arrive at a very high cost of implementation.
– Risk of backup tapes
Normally the units also do not have a safe place for storage of tapes, leaving the data at risk in cases of disaster such as fire, theft or flood.
