Set bandwidth for laptop backups

inSync Private Cloud Editions: File:/tick.png Elite File:/tick.png Enterprise

Overview

During backups or syncs, data is transferred from the devices to the inSync storage. These data transfers consume bandwidth. As an administrator, you can limit the bandwidth that inSync consumes for backing up data. This ensures that all applications on the user’s laptop get a fair share of the available network bandwidth even during backups. A lower bandwidth can result in prolonged backups. You can limit bandwidth either as a percentage of the available bandwidth or in absolute terms. If you limit bandwidth in percentage terms, inSync will calculate the bandwidth available to it before starting the backup and then utilize the configured percentage of it.

Note: You can set network bandwidth for inSync through profiles. You cannot do this on an individual user level.

Important points to consider:

  • The bandwidth limitation is for each inSync client on the user device and not for inSync Master as a whole.
  • We recommend using percentage values instead of setting limitations in absolute terms. For example, instead of limiting the bandwidth to 256 kbps, set the limit as 40% of the available bandwidth. This ensures fair distribution even while there are fluctuations in the available bandwidth.
  • Before the first backup from all devices are complete, keep 80% as the maximum bandwidth consumption limit. Once the first backups are complete, you can reduce the bandwidth to reduce 40%. The first backup is a complete backup and transfers large amount of data. Subsequent backups transfer only the incremental data.

Procedure

To limit the network bandwidth that inSync consumes during backup

  1. On the inSync Master Management Console menu bar, click Manage > Profiles.
  2. Click the link of the profile for which you want to limit the network bandwidth that inSync consumes during backup or sync.
  3. Click the Laptop Backup Schedule tab.
  4. In the Laptop Backup Resources area, click Edit. The Edit Profile window appears.
  5. In the Max Bandwidth [LAN] list, type the maximum network bandwidth that the user devices can consume while backing up data over LAN. If you do not want to set any restriction on bandwidth consumption, type 0 (zero).
  6. In the Max Bandwidth [WAN] list, type the maximum network bandwidth that the user devices can consume while backing up data over WAN. If you do not want to set any restriction on bandwidth consumption, type 0 (zero).
  7. Click Save.
