What is Archive Cleanup?

Archive Cleanup does a one-to-one match of the local data in the backup set selected for cleanup with your account files, and permanently deletes data from your account that no longer exists on your NAS device. This frees up space in your IDrive account.

By default, Archive Cleanup considers 25% of files for deletion. You can also regulate the percentage according to your preference.

When I am logging in to my IDrive account for the first time on a new Synology machine, it is asking me to select location/computer for backup. Why?

IDrive allows you to restore your previous computer's backup archive on your new computer. You can select the 'Adopt/Link to an existing location/computer' option for this. After logging in, reconnect to the previous computer's backup archive in case you are replacing an old computer. By adopting the previous computer's backup archive, you can avoid time consuming initial backup of your files.

To adopt your backup archive,

  1. Install Synology backup app in your NAS machine and login to Synology Backup App.
  2. Click 'Adopt/Link to an existing location/computer' when prompted to select location/computer for backup. A list of locations/computers linked to your account appears.


  3. Select the desired computer/location from the list and click 'Adopt/Link Selected Location' to restore your previous backups.



In case you do not wish to adopt your previous backups on the new machine, you can click 'Proceed to create new location with this computer name' when prompted to select location/computer for backup.

Can I login to another IDrive account while already logged in to the Synology app?

Yes, you can switch from one IDrive account to another.

To switch accounts,

  1. Click the username on the top-right corner, and then click 'Preferences'.
  2. Click 'Logout' in the 'IDrive Cloud Account Credentials' section.
  3. Enter the other account credentials and click 'Login'.

Why is the CPU load becoming high while running backup/restore?

If you have enabled the 'Upload multiple file chunks simultaneously' option under 'Preferences', backup or restore will consume a little more load than expected, as this option speeds up data transfer by using multiple thread concept. You can disable this option if your machine resource utilizations are higher.

I am unable to create backup sets. Why?

If you have already created five backup sets you will not be able to create any new backup sets further. In order to add a new backup set, you will have to delete any of the existing sets.

My data backed up to the express device is not visible under 'Restore files from my local device' section in the 'Restore' tab. What should I do?

Files backed up to your Express device appear under the 'Restore files from my local device' section in the 'Restore' tab. If you are unable to view data backed up to your Express device, then you can run 'Re-index' operation. This will re-generate the file/folder list with all the backed up data.

Note: When Re-index operation is in progress then you will not be able to perform local restore/express backup.


Will I be able to backup data to the Express device without internet connectivity?

Express backup does not require an active internet connection. If you are already logged in to the IDrive application then you can run backup even when your machine is not connected to the internet.

Note: For logging in to the IDrive application an active internet connection is required.
