How to track card changing?

[Markiyan]

My team is going to use Trello. But we need to be sure that there is minimal chance to lose data there. So my questions are:

• How to disallow deleting a card? ( change permissions of deleting, not archiving )
• If all members of a team need to be able to change a card, how to track these changes? ( especially we can't see the changes of title and description of the card )
• What if someone accidentally changes a title? How can we restore previous title?

Hey Markiyan

• Trello doesn't have functionality to disable someone's ability to delete a card. Any member of the board will be able to archive/delete a card.  When a card is archived and/or deleted, it will be displayed in the board activity log.
• Descriptions and titles aren't currently tracked in activity history.  The workaround would be to use Butler Bot automation.  Butler will comment on a card with those changes, when you set it up.  See below for setup for this
• Here's some guidance on recovering changes: https://help.trello.com/article/783-recovering-the-description-of-a-card-that-has-been-changed

To add custom automation using Butlerbot, follow these steps:

1) Add Butlerbot to your board here: https://www.butlerfortrello.com/dashboard.html
-- A new list will be created titled "Butler"
2) Add two new cards to the Butler list, using the below text. Each card serves as a command

when the description of a card is changed, post comment "{username} changed the description on this card from '{textbefore}' to '{textafter}' on {date} at {time}"

and

when the title of a card changes, post comment "{username} changed the title of this card from '{textbefore}' to '{textafter}'  on {date} at {time}"

Let me know if you have any further questions about setting this up.

PS: Butler prefers that you use the Butler Power Up, which has a lot of automation available.. but in this case the bot would need to be used.  Here's Butler's command builder: https://butlerfortrello.com/builder.html and here's Butler's sample board: https://trello.com/b/2dLsEE9t/butler-for-trello
