Time Machine backups are unfussy: unlike many proprietary backup software packages, you can browse a Time Machine backup either through its interface or via the drive in the Finder. However, it appears as if every backup is a complete backup. This concerned Macworld reader Peter, who just purchased a new iMac and a 4TB external drive to use with Time Machine. “This is going to fill up my external drive fairly quickly,” he worries. Time Machine just looks like it’s making a full backup every time it creates one, but it’s really using a clever technique to only copy changed files at each hourly interval. While Time Machine’s method has been the same since its introduction, it’s opaque to most users, because it’s meant to work without requiring any maintenance or fussing. (In fact, that’s a flaw, too, because there are no tools to fix corruption or control any of the settings, like frequency and purging of older files.) Time Machine only … [Read more...] about Does Time Machine back up every file every time?

Connected Data, creator of the Drobo line of Network Attached Storage (NAS) devices has released a software update for its newer devices that will be interesting to Time Machine users. The company has announced updated Drobo software for the Drobo 5D and Drobo mini that allow them to be used for Time Machine backups. The update comes in the form of new firmware (v.3.1.1) and a new version of the Drobo dashboard software (v.2.6.2) that allows certain Drobo devices to be seen by Apple's Time Machine software. The new feature is limited to the company's Drobo Direct Attached models, which include the Drobo mini and Drobo 5D. To make a Drobo Time Machine capable you need to create a dedicated, fixed capacity volume for Time Machine within Drobo Dashboard. This can be done without disturbing your existing data. Within Drobo Dashboard just click on Volumes (in the left navigation) then on the button for "Enable Backup/Time Machine volume" (above). The next screen asks what … [Read more...] about Drobo adds Time Machine support
When it comes time to dissect a network problem, whether the problem is related to security or performance, a deep look into all the network activity surrounding the incident can be critical to resolving the issue. An intrusion detection system, with its rules for capturing problematic network events, can be of some help, but for real problem diagnosis or forensics, you need more. Network Instruments' GigaStor is designed to meet that need with full traffic capture that extends backward to hours or days. This "keep it all" capability makes the GigaStor a valuable addition to any network for which high performance, security, or regulatory compliance are critical issues. When you need to investigate a network slowdown, a security breach, or anything else that happened on your network, if you know when it happened, then GigaStor can take you there. GigaStor is, essentially, a large box of great storage capacity (from 4TB to 48TB) with high-speed network interfaces on the outside and the … [Read more...] about A time machine for your network

Predicting when hard disks will fail is an inexact science, but a researcher from the University of Nebraska may be close to making it more accurate.Enterprise storage arrays, whether arranged in SAN, NAS, or object configurations, can contain dozens or hundreds of individual hard disks. More precise insight into which disk may soon fail, even if it's just an improvement of a few percent, could mean the difference between proactively keeping multiple terabytes of data online or reactively retrieving it from backups. Junjie Qian, a doctoral student in computer science, said his approach to predicting soon-to-fail disks works by using multiple machine-learning algorithms. Existing approaches use only one model, which suffices but causes too many false positive results, he said.Qian, whose work is sponsored by NetApp, presented his research in Boston last month at the IEEE Conference on Networking, Architecture, and Storage. "To the best of our knowledge, industry and academic … [Read more...] about Hard disk failure prediction research may save IT time and money
Earl Jarrett asks a question many people have about Time Machine backups. He’s currently using a 1TB external drive and wants to upgrade to a new 4TB drive. Time Machine can keep a deep history of your previous versions, and the more space, the deeper the history, which has led many people to upgrade the storage they allot to these bakcups.How do I transfer the info from the 1TB external drive to a new 4TB external drive and use it with Time Machine, and then wipe the 1TB drive and use it to run Photos while making sure that any new pictures are backed up as well?It’s fairly easy, but requires that you perform a number of actions in the right sequence to ensure no backups are in progress while you’re copying.Disable Time Machine from its menu item or via the Time Machine system preference pane.Mount both drives.Launch Disk Utility to check that the new drive is formatted correctly in the next two steps.Click the new drive’s icon in the left bar, and make sure … [Read more...] about How to transfer a Time Machine backup to another backup drive
Dawn Gwin asked:I replaced my seven-year-old Time Capsule with a new one last week. Can I erase the old one and connect it by ethernet occasionally to serve as a second backup kept off premises? Or would I be better off with just a flash drive for important files?The networked Time Capsule base station/backup combo doesn’t have a great track record for long-term survival. I’m surprised it’s lasted seven years, and you might not want to push your luck with it. At a minimum, you’d want to wipe its network settings so that it doesn’t confuse your existing devices into which base station is which. Then you can just plug it in as needed.A better solution for a secondary backup you can rotate out is a portable hard drive connected either to a Mac on the network or a Wi-Fi router from someone other than Apple that supports USB 3.0 drive connections and is Time Machine compatible. You can get terabytes of storage in a portable hard drive format with a USB 3.0 … [Read more...] about Should you keep using an old Time Capsule to rotate for off-site storage?
