We Love Feedback

We gather feedback from a lot of sources: Cucku Support, Twitter, Facebook, our new LinkedIn Group, this blog and a survey sent out to everyone who creates a Cucku Account and allows us to send email.

One thing that's been missing is the ability for Cucku Backup customers to share ideas with each other as well as with us directly. To correct this we've just launched a feedback forum for Cucku:



The forum is powered by the excellent UserVoice - you may well be familiar with how this works from other sites. You get ten votes which you can use to either add new suggestions or vote on existing ones.

Cucku staff will be active in the forums - as well as voting you can discuss the suggestions and we'll be there to provide feedback and clarify requirements before we accept and implement new features.

The forum isn't designed for reporting problems and bugs - if you're having trouble with Cucku Backup or Cucku Backup Pro you should still open a support ticket.

I've added a few items to get the discussion started. Visit feedback.cucku.com to join in.

When did you first "get" backup?

It was a dark and stormy night...

Actually it was a sunny day in Virginia. I was twelve years old and committed to writing a novel using Paperback Writer on a Commodore 64:



There was no auto-save, no quick Ctrl-S, just waiting to write the file to the lumbering 5¼ inch floppy drive. Inevitably five hours after the last save the computer crashed and everything was lost.

Tears before bedtime, lesson learned about backup and I don't think I ever ran Paperback Writer again.

I think everyone who really "gets" backup has a similar tale. Let me know your story - what was your first or worst case of data loss?

Backup and System Performance

The default settings in Cucku Backup are designed to balance protection and performance. You can tune these settings to get the right mix for your needs.

The first thing to look at is the Backup Schedule:



The default is to backup your computer every day when the computer is idle. After the local backup completes Cucku will send new and changed files to each of your backup partners. You can change the schedule to run a local backup weekly rather than daily which will reduce the load of both local and remote backup.

With Don't backup while I'm using my computer checked Cucku will wait until your computer has been idle for ten minutes before starting a local backup. If you start using your computer again while the local backup is running Cucku will automatically pause the backup until the computer is idle again (you can change the ten minute idle timeout in Advanced -> Performance).

By default Cucku will run remote backup while you're using your computer. It will also accept backup connection from your partners. You can change this in Partner Settings - check Don't send or receive files while I'm using my computer and remote backup will behave the same way as the local backup default.

If you need even more control then you can decide when to run Cucku, or even run a command line backup.

In Advanced -> Performance uncheck Run Cucku Backup at startup to prevent Cucku from running when you log in to Windows. We really don't recommend this as you need to remember to run Cucku manually and your partners can't connect when Cucku isn't running.

If you don't want Cucku running all the time then a better option is to schedule the command line version of Cucku to run daily, weekly or on whatever schedule works best for you. The command line is capable of running local, remote and partner backups.

Is there anything else we should be doing to help you get the right balance between protection and performance?

Is my Hard Drive About to Fail?

Yes.

Longer answer - all drives fail eventually. I'm starting to get a little nervous because my main system hard drive is nearly five years old. It's had a good run, but the odds are starting to stack up against it.

Google published Failure Trends in a Large Disk Drive Population a couple of years ago. The (possibly) surprising conclusion of the paper was that drive temperature and activity are less important factors in predicting a drive failure than the presence of any errors.

The chart below (from the Google paper) shows the average failure rate for drives with no scan errors and drives reporting one more more scan errors (hard drives scan their surface in the background and report any errors found):



The paper goes on to say:

The critical threshold analysis confirms what the charts visually imply: the critical threshold for scan errors is one. After the first scan error, drives are 39 times more likely to fail within 60 days than drives without scan errors.

It's interesting to note the much higher failure rate in the first six months. Google attributes this to an "infant mortality phenomenon" - some drives are lemons.

The same pattern repeats itself for several other factors including reallocation, where the contents of a bad sector are moved to a new, good sector and probation, when the drive suspects that a sector might be a troublemaker in the future.

All this suggests that you should take action at the very first sign of trouble with your hard drive. Counter-intuitively this advice is even more important if your drive is brand new. I'm going to buy a new drive for my system and use my five year old for less important data.

Why do I need a Local Backup?

With your files safely backed up offsite you might wonder if local backup is about to become extinct. A few Cucku Backup customers have event asked us to provide an option to have remote backup without local backup - in some cases because of low disk space and in others because they lack an external hard drive.

Most online backup companies work this way. You wait weeks or months while your backup trickles into the cloud and then hope that your provider doesn't go bust or lose your data.

We believe in a belt and braces approach. A full local backup protects you from everyday data loss and a remote backup is there in case of a true disaster. Right now you can pick up a 500GB external drive for less than $100. Add Cucku Backup, free for a single backup partner and you're fully covered.

File Backup vs. Disk Image Backup

There are two main approaches to backing up your computer - selectively backing up files and folders or imaging your entire hard drive. Both have advantages and disadvantages.

File level backup lets you focus on saving irreplaceable data and reduces the space needed to store the backup. In the event of a disaster you'll need to reinstall your operating system before you can restore data. You also need to be careful to ensure that all of your data is included in the backup.

A disk image includes everything on your hard drive - the operating system, applications and your data. You know that you're fully covered but at the expense of space and time. You can also run into trouble if you need to restore to a new computer as a disk image will also restore drivers and settings for the original computer.

Like all online backup software Cucku takes the first approach - we backup the files that you can't replace. You can always reinstall Windows and your applications and if necessary you can buy a new computer. Your personal data is different and you need both local and remote backup - belt and braces - to ensure that it's protected.

Personally I relish the chance to reinstall my computer. Over time you build up Windows cruft, applications you no longer run, setting and registry errors and other problems that slow your computer down. When I buy a new computer I start by reinstalling the OS to get rid of the various bundled applications (and to make sure I know how to get it up and running in case I need to recover the system later).

Which backup philosophy do you prefer? Do you think there's a place for disk images in online backup?

Windows 7 Backup - How Microsoft Should Improve the Action Center

Windows Security Center has nagged you about anti-virus, firewalls and automatic updates since Windows XP SP2. I've always been puzzled that backup wasn't included on the list - you can have a happy green shield while remaining vulnerable to data loss.

Windows 7 takes a baby step forward with the new Action Center. This includes both security and maintenance tasks and I was happy to see a prompt to configure backup:



Disappointingly though the backup item isn't flagged as important and the only option is Microsoft's backup tool. This is much improved over the default Vista backup but it's still a simple local backup tool.

Backup is a critical security component and Microsoft should take the following steps to ensure that users find and use the right backup product for their needs:

1. Backup should be a first class citizen in the Action Center. If backup isn't configured or a backup hasn't occurred recently this should be treated as an important security warning.


2. As with other security components Action Center should include a Find a program online button to guide the user to a selection of backup products from reputable vendors.


3. Microsoft should extend the Security Center/Action Center API to allow third party backup products to report their status to Windows.
