Your QuickBooks Company file grows as you enter transactions, and as part of that process, it also maintains a transaction log file (.TLG) which grows and is maintained in case there is data corruption, Intuit Recovery Services can use this file to help recover your data. This file can get really large, exponentially larger than your actual Company File (.QBW).
As a result, the likelihood of data corruption, and performance issues will increase. While you may be taking a backup to your local workstation via FileBridge, or even to the server, it is important that this special type of backup is done, which is the option with "Complete Verification". This backup can only be done in Single User Mode, while no other users are connected to the Company File.
Your server will have a path specifically for each of your Company Files in the following path: Q:\<Company Prefix> Backup\<Company File Name>
Depending on the size of your Company File, this type of backup might take a while to complete the verification and perform the backup, but once it completes, it will also truncate the size of the TLG file from possible multiple Gb to 320Kb or a bit larger than that.
It is very easy to perform this backup:
