Sage Timeslips offers a Scheduled Backup feature which will help automate the Timeslips database backup process. However, the current Scheduled Backup feature uses the Windows Task Scheduler to execute a Windows batch file which does not include any code limiting the number of backups it creates. I tried contacting Sage support about this but they have no solution at the present moment. Perhaps by the time you are reading this they have one.
In this article I cover what I did to limit the number of Sage Timeslips database backup copies stored within the Backups directory of my client’s computer. Note that I do not work for nor am I in any way affiliated with the Sage company. The information herein is for my personal use only so that I can recall what I did should the need arise. You can hire me to assist you with your Timeslips database backups remotely by contacting me.
If you do not know what you are doing with Windows batch files you may inadvertently and permanently delete important system files or lose vital data. Especially if you fail to properly backup your data and computer. You’ve been warned!

For those serious about security on their Raspberry Pi 4 computers, regularly clearing the terminal history or bash history is advisable.
A chronological history of your entered terminal commands is automatically retained, which is great when you need to repeat or lookup a prior command. However, this can also become a security concern. What if someone gains access to your machine, opens a terminal window, and browses through your terminal history? If you are human, no doubt you will have (at some point) accidentally entered a password in a non-password field.
This article will show you how to quickly and easily clear the history of your terminal window.
