Avast BackUp: Frequently Asked Questions - Performance
Why does Avast BackUp show a different quota on the website than it does in the client?

The Avast BackUp hasn't updated with our servers yet. To update your quota, proceed as follows:

  1. Right-click the Avast BackUp icon in your system tray, then select 'Settings'.
  2. When you connect to the Avast BackUp Servers during this process, your quota value in the Avast BackUp client is updated. There are few cases where you have to reboot or start a backup before the correct amount is shown.

Avast BackUp seems to bog down my system. Is there a way to fix this?

There are two places you can tell Avast BackUp to use fewer computer resources:

  1. First, there is a slider bar that you can move between Faster Computer and Quicker Backups while backing up. If you move it toward Faster Computer, the backup slows down and the computer speeds up. It may take it a minute to take effect.
  2. Or secondly, click the 'Configure' button on the main Avast BackUp window (it comes up when you double click the Avast BackUp icon by your clock in the system tray), and select the 'Options' tab. You should see a section labeled Backup Speed containing a slider bar that you can move between Faster Computer and Quicker Backups. If you move it toward Faster Computer, the backup slows down and the computer speeds up after you click the 'Save' button. It may take it a minute to take effect.

If these slider bars don't show up, then upgrade to the latest version of Avast BackUp.


The Start Backup button is grayed out. How do I start my backup?

The 'Start Backup' button is usually only grayed out when there is a problem with the Avast BackUp service. To restart the service, simply restart your computer.

Windows users can also try this:

  1. Click your Start menu, then select 'Run'.
  2. Type ' cmd ' and click 'OK'.
  3. In the command prompt, type ' net stop Avast BackUp Backup Service ' then press Enter.
  4. In the command prompt, type ' net start Avast BackUp Backup Service ' then press Enter.
  5. Check to see if the button is still gray.

Avast BackUp is not uploading data fast enough.

Typical upload speeds to our servers for domestic (U.S.) connections are in the 200-500 kbit/sec range. If you get more than this, congratulations! If you get a lot less than this, then you should check your favorite bandwidth meter test to measure your broadband connection. The "upload" part of the test is what matters for Avast BackUp usage. When picking a server to test, pick anything that's not on the East Coast and you will get a pretty good approximation, since most of our servers are located in the western United States.

After your initial backup, subsequent backups are relatively quick. Chances are that you won't even notice them. This is possible because Avast BackUp performs what are called differential backups, which means that it only backs up the portions of your files that have changed since the last time they were backed up. This saves lots of time, bandwidth and storage space.

During installation, Avast BackUp runs a bandwidth test and lets you know about how much you can upload a day. But if you want to get an estimate of the transfer rate before you begin your initial backup, you may want to use a bandwidth meter to measure your broadband connection speed. We recommend using the meter from Speakeasy.


Why do I keep getting a ConnectionError1?

There are two common issues which may cause this error. First, your firewall is not configured to allow Avast BackUp through. You can verify this by temporarily disabling your firewall and trying to perform a backup. If Avast BackUp is able to back up when your firewall is disabled, then you've confirmed that it's a firewall problem. For more instructions see:

Second, if you have scheduled your backups at the top of the hour (such as 12:00 or 3:00), we may be experiencing excessive congestion which may cause the connection to time out. To resolve this try scheduling your backups just off the top of the hour (such as 12:07 or 2:53). If Avast BackUp still gives ConnectionError1 errors, then something else is wrong and you should contact customer support via Avast Support Center.



Using Avast BackUp with a Firewall

If you have a firewall, you will need to configure it to let Avast BackUp through.

Avast BackUp backs your data up by making a secure TCP connection over the Internet to the Avast BackUp servers. This will usually trigger firewall software, which will simply ask you if you want to let it through. Since backups happen automatically throughout the day, select the option that will always allow it access.

Sometimes firewall software does not prompt you and blocks Avast BackUp by default. In that case, you need to manually configure your firewall.

If you are an expert firewall administrator, you can configure it with the following settings:

  • avastBackUpconf.exe ( Avast BackUp Settings), open outbound port 443
  • avastBackUpstat.exe ( Avast BackUp Status), open outbound port 443


For example, if you are using Avast BackUp with Windows Firewall (Windows Security Center) proceed as follows:

  1. Open Windows Firewall from one of the following locations:
    • Click Start menu > 'Control Panel' > 'Windows Security Center' (if New Start Menu is used).
    • Click Start menu > 'Settings' > 'Control Panel' > 'Security Center' (if Classic Start Menu is used).
  2. In the Windows Security Center window, click on Windows Firewall under Manage security settings.
  3. In the Windows Firewall Screen, select the 'Exceptions' tab. In the 'Exceptions' tab, you can add programs that Windows Firewall will allow to access the internet. Avast BackUp uses TCP to back up your data.
  4. Click 'Add Program'.
  5. From the list of programs that appear, select avastBackUpconf.exe ( Avast BackUp Settings) and click 'OK'. If you do not see avastBackUpconf.exe listed, click on the 'Browse' button, and navigate to the folder where Avast BackUp is installed. Select it and press 'Open' to add it to the list of programs.
  6. In the Add a Program screen, select avastBackUpconf.exe and click 'OK' to add it to the list of programs allowed to access the internet from your computer. In the 'Exceptions' tab on the Windows Firewall screen, avastBackUpconf.exe ( Avast BackUp Settings) appears with a checkmark next to it.
  7. Repeat last two steps and add also avastBackUpstat.exe to the exceptions in the Windows Firewall.
