My last blog post was a high level discussion about understanding your data and creating a plan around it. Now let’s take a look at Arcserve Unified Data Protection (UDP) and what features it has to help you.
UDP is a disk based solution, meaning that your backup target will be some type of disk device (NAS/DAS/SAN etc…). You do have the option of then moving the data of to tape if you have need for long term retention. It also supports moving data off to the cloud as well in the case that you do not want to deal with tapes. If you have a co-location then there is replication built into the product to move the data from one location to another and even gives you the ability for different retention settings at the different locations.
UDP is an image based backup solution that utilizes VSS for Windows and our own imaging technology for Linux. This means you will be protecting your data at a volume level no at a file level. Imaging tends to be a much faster solution than file level backup and can typical be done throughout the day instead of at the end of every day. This bundled with the capability to do infinite incremental backups means that you can get a much more granular level of protection.
Let’s talk about infinite incremental backups and what they bring to the table. With a traditional backup you typically perform incremental or differential backups throughout the week and a full backup at the end of the week. Depending on the amount of data full backups can take a bit of time and sometimes completing full backups in time can be a real challenge. Infinite incremental backups can address this by removing the need to do full backups.
With infinite incremental backups you can now schedule backups to occur more frequently than traditional backups. You may choose to go a granular as every 15 minutes provided your data change supports that. This will open up your recovery options allowing you a much more granular set of recovery points.
Putting backups on disk is good, easy, and what a lot of companies are looking for today. There can still be cost concerns with disks so you should look at a way to minimize the amount of disk storage required. UDP does this by utilizing source side global deduplication. First the data will be deduplicated at the source, next global deduplication occurs comparing the data to all the other data residing at the destination. This will not only reduce the amount of disk required but also reduced the network traffic being utilized for backup.
In my next blog post I will cover the Virtual Standby and Full System High Availability features of UDP. The differences and why you would choose one over the other. Until then may all your backups be fast and all your restores be true.
