Making informed decisions on data deduplication, continuous data protection (CDP) and replication technologies can be a crucial first step in ensuring effective backup processes. To find out more about backup strategies and tools, data reduction technologies, and the advantages of disk- and tape-based backup, read the following data backup and recovery tips.
How does data deduplication impact backup?
Data deduplication impacts backups in different ways depending on the technology deployed. There are essentially two options: deduplication at the client side and deduplication at the back-end disk target. Learn about the positive impacts both of these options can have on backups, including eliminating data residing in backup systems to free up space and use less energy.
UK users turn to email archiving for e-discovery, auditing and backup help
UK users are beginning to turn to email archiving to help them deal with e-discovery and backup, auditing concerns and mailbox administration load. Find out why data centre managers at Brunel University, London taxi firm Addison Lee and high-tech PR agency Johnson King implemented email archiving systems, discover their implementation tips and learn how the technology has benefitted each firm.
When is the right time to switch from tape to disk-based backup?
While the price of disk decreases daily, the cost of tape does not. So for many organisations, the switch from tape to disk-based backup is on the agenda. However, businesses need to consider the bigger picture before making the switch, because the correct time to move is dependent on numerous organisational drivers.
IT professionals explore disk-based backup, data deduplication to speed backup
As data storage capacity continues to grow, so do the size of backup windows -- a challenge that is prompting many users to consider disk-based backup products and data deduplication. At the Storage Decisions Advanced Backup School, storage pros agreed that data deduplication and greater use of disk are promising solutions to increase backup speeds.
Evaluating a data deduplication product for data backup and recovery
As more organisations implement disk-based data backup and recovery to overcome the shortcomings of tape-based data backup, data deduplication has emerged as a force to improve the economic feasibility of retaining data longer on disk. When evaluating a data deduplication product, cost, performance, scalability and the deduplication domain are just a few of the considerations. Discover what else you need to consider when buying a dedupe product.
Understanding data deduplication ratios in backup systems
The effectiveness of data deduplication is often expressed as a deduplication or reduction ratio. However, understanding these ratios can be very confusing. Learn how to estimate a realistic data deduplication ratio in your backup system and discover best practices for evaluating a dedupe product in this tip.
Data deduplication: The business case for dedupe
What makes data deduplication a justified expenditure in one environment will not necessarily hold true in all environments; there is definitely a need to understand whether dedupe will fill a gap, help you meet a requirement or reduce costs. This tip will help you decide if data dedupe is right for your business.
Troubleshooting data backup error log messages
For many storage/backup administrators, one of the first things they do in the morning is change backup tapes and verify that the backup ran correctly the night before. Although backups tend to be a lot more reliable than they used to be, there is always the chance that you may discover that there was a problem with the backup. Knowing how to read your data backup error log messages can help you save time fixing common backup problems.
Linux data backup and recovery strategies
Linux data backup products are adding new capabilities and becoming even more mainstream. Today, most major storage management vendors such as Hewlett-Packard (HP) Co. and Symantec Corp. have Linux versions of their storage management tools. Learn about various Linux backup and recovery strategies, including using Linux backup for virtual machines.
A comparison of data backup software packages and their integration with VMware
Server virtualisation has changed the way you back up and restore data. You can still use traditional backup methods for virtual machines by using a backup agent on each virtual machine, but there are more efficient methods to back up virtual machines. If you're trying to decide which backup software to use with VMware Inc. Infrastructure 3 (VI3), take a look at how some of the major data backup software packages integrate with VI3.
Alternatives to tape-based backup and archival systems
Although many organisations are still using tape for archiving, backup is increasingly moving away from tape. If you are having problems meeting your backup window, perhaps it is time to choose a backup method other than tape. Here is a look at alternatives to tape-based backup.
How to decide what data to back up
Deciding what data to back up can be a delicate balancing act for backup administrators. You probably have a limited backup capacity and a limited backup window during which to complete your data backups. At the same time, you have to back up enough data to meet your company's recovery needs. We provide you with a list of considerations to help you decide what data you need to back up.
