Backup Tools

Backup ToolsIf there’s one thing that keeps IT Managers and business owners awake at night it is the thought of catastrophic data loss, typically due to hardware failure but it could also be due to failed software upgrades , database updates, human error or even malicious hackers. So in order to sleep better it is of course essential to have good backup tools.

Backups can be done in many ways, even manually with a simple copy command, however manually created backups are not something to be relied on because it is only a matter of time before a backup is forgotten or it fails to include some essential data and you may never know about it until you need it and find your critical data is not there. You do not want that to happen! Proper backup tools which are automatically run on schedule and which make incremental backups containing data updates and additions along with periodical full backups with all your data are the order of the day. There are quite a few solutions which provide just this, as you would expect as backups are not a new thing, some of which are software you must install and manage, some are complex backup server systems and some are remotely managed services so you only have to deal with defining what and when to backup and the rest is done for you.

For Linux based systems a popular backup utility is rsnapshot which is basically just a Perl script that wraps around rsync and is run by cron every hour or at intervals you define. It creates the incremental backups as you would expect and rotates them all for you. Once configured it works well. It does of course depend on your own backup hardware and you need to make sure it is configured correctly and actually runs as and when required.

For a more ‘enterprise’ level backup system you could use something like Bacula which is an open source system featuring a linux/unix based server along with client daemons which run on multiple OS’s including Windows.

Once you have a backup system in place you need to know it is actually running and doing its job so you could use your monitoring tools to keep an eye on it and alert you if things go wrong so you can hopefully fix it long before you ever need to access your backed up data.

So called ‘Cloud’ backup tools are another option and there are many to choose from, quite a few of which depend on Cloud storage systems such as AWS (Amazon). Having your data managed and hosted by another company may be something you would need to consider carefully for various reasons from legal to security. Is your data secure there and do your terms of service or client contracts allow you to store data in such a way? There are undoubtedly benefits to using a managed backup service but make sure to do your due diligence before trusting your precious data to a 3rd party. Services for MSP’s to consider include Kaseya, Datto and GFI, amongst others.

Either way it is certainly wise to have more than one backup location anyway so your backups do not go up in smoke along with your primary systems!

Whichever backup tools you choose to use you also need to make sure that you can get your data back from your backups should you ever need to. It is essential to test that your backups are working and the right data from the appropriate snapshots is easily and quickly available – data recovery is just as important as data backup!
