IT infrastructure and systems have become increasingly critical to the efficiency of all businesses and the economy as a whole. For businesses, the potential consequences of a major data loss are frightening. Recent statistics show that of the SMEs who experienced a major data loss, 43% never reopened, 51% closed within two years and only 6% survived in the long-term. Notwithstanding this, best estimates are that only 2% to 4% of the average IT budget is allocated to disaster recovery planning. Advance planning avoids potentially greater losses in the future.  Despite the most sophisticated protection and precautions IT infrastructures do fail and advance preparation should be taken seriously.

At Aalto, we have the expertise and experience to provide you with rapid disaster recovery systems that could be crucial to the continued operation of your IT infrastructure and your business. We are based in Johannesburg and service the greater Gauteng area.

Data Backups

Backups of your data are essential to restoring lost information and there are various ways to achieve this. In most instances, we recommend two or more of the following

On-site

A primary on-site device is essential in all circumstances. On the hardware side, we have found HP or Quantum LTO storage drives to outclass the competition, while Symantec Backup Exec or Acronis Backup and Recovery receive our best rating for storage management software. There are many others options that may be cheaper, for instance using an external hard drive, but these should never be considered for your primary source.

NAS (Networked Attached Storage) devices

NAS devices provide a good secondary alternative. In the past, these were beyond the reach of most small businesses, but prices have declined and now their use is common. We recommend Seagate Black Armour NAS 440 or Western Digital ShareSpace. Both come with RAID-5, which also provides  redundancy of data protection.

Off-site

It is advisable to maintain at least one off-site backup. Contact us to discuss a feasible option suited to your business, e.g.

Cloud Backup

“In the Cloud” or remote online backup facilities are becoming more popular. This backup strategy involves sending a copy of the data over a proprietary or public network to an off-site server. Usually, a third party, who charges a fee based on capacity, bandwidth or number of users, hosts the server. Typically, these services are built to accommodate client software, which is scheduled to run at regular intervals. For example, if you have contracted for daily backups, the application collects, compresses, encrypts and transfers data to the provider's servers every 24 hours. To reduce the consumption of bandwidth and transfer time, incremental backups follow the initial full backup.

Cloud backup provides a very convenient secondary alternative as they run automatically and require no manual intervention. Additionally, no hardware is required, reducing capital expenditure. These services can also be used as a primary source for archiving non-critical data.   

Data Redundancy

Data redundancy forms an integral part of our disaster recovery recommendations. In basic terms, data redundancy means that data is stored twice (mirrored) and that data can be derived or restored from other data. Besides backup systems, it is an additional failsafe to ensure the recovery of your most valuable digital asset. All our current installations and sites have redundancy policies in place, and the NAS devices mentioned above come standard with RAID-5, which employs disk arrays.

Disk arrays can withstand hard disk failure, without any data loss. Restoration happens automatically and replacement from backups is unnecessary. Data is also examined and corrected to prevent corrupted duplications or modifications.

Your data is your most important business asset and we have the capabilities to protect it from disaster.

Protecting your data through disaster prevention!

network security

Today, your network is also vulnerable to worms, trojans and other malware that require additional anti-virus software and intrusion-prevention systems to prevent and destroy these malicious attacks. Protection can be increased by adding a security token or certificate to the authentication process, and thereafter a fingerprint or retinal scan in appropriate circumstances.
