If for some reason you mi migrate your data to a new computer, consider the following recommendations:

Computers running on 32-bit Windows are limited to 4 GB of RAM and may experience some memory issues caused by this limitation. To avoid (not guaranteed) the occurrence these issues, consider to set the following restrictions:

  • Set a decrease memory limit
  • Decrease thread count/chunk size.

Decrease Memory Limit

To decrease the memory limit, proceed as follows:

  1. In the Tools menu, click Options.
  2. Switch to the Memory Options tab.

  1. Deselect the Automatic check box (if selected), then lower the Maximum Memory Usage counter. For example, set 150 MB.
  2. Deselect the Unlimited check box (if selected), then lower the Maximum Disk Usage counter. For example, set 700 MB.
  3. Once you are done, click OK.

Decrease Thread Count and Chunk Size

While processing backup data in memory, MSP360 (CloudBerry) Backup breaks files into chunks of a certain size.

To set new values for thread count and chunk size, proceed as follows:

  1. In the Tools menu, click Options.
  2. Switch to the Advanced tab.

  1. In the Chunk Size counter, specify the lower value. For example, 2MB.
  2. In the Thread Count counter, specify the lower value as well. For example, 4. This setting limits the number of simultaneous threads for one backup plan to the specified number.
  3. Click OK or Apply.
