Description

  • What determines how long it takes to restore data using N-able Backup?

Environment

  • N-able Backup
  • Restore

Solution

  • Restore time will depend, almost exclusively, on local environmental factors, which include the target device's ability to download and process data. Below is a list of some of the more significant and common environmental factors:
    • Processor speed
    • Processor type (server CPUs will generally work through the download/decrypt/decompress jobs faster than desktop CPUs)
    • Available RAM
    • Local bandwidth
    • Disk write speed
    • Target disk I/O limits
    • Non-local disk transfer speeds (e.g. if restoring to iSCSI or SAN)
  • A rudimentary "theoretical best" download time can be calculated using online calculators, such as this. However times generated this way aren't able to factor in the majority of the vital variables that impact the actual restore time which are listed above.
