Backup of Timescaledb running on a seperate container using pgbackrest

[BilalS10]

** Which example are you working with? **
I have a timescaledb container running via a docker compose file. I want to know if there is a way to run the crunchy data container along with it to just take the backup of this timescaledb container using pgbackrest. If yes, what are the steps for the same.
I can see there are multiple containers available on the crunchy data official page (crunchy-pgbackrest, crunchy-pgbackrest-repo)..
but from the documentation it seems, Ill have to use a crunchy data container for my timescaledb.

Please tell us about your environment:

• Operating System: Debian 10
• Where is this running: Local
• Container Image Tag: Timescaledb 2.5.2
• PostgreSQL Version: 13.5
• Platform: Docker

Thank you
