Data rotation and cleanup in Raspberry Pi - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is data rotation in the context of Raspberry Pi?

Data rotation means regularly moving or renaming old data files so new data can be saved without using too much space. It helps keep storage clean and organized.

Why is cleanup important after data rotation?

Cleanup removes old or unnecessary files after rotation to free up storage space and keep the system running smoothly.

beginner

Which Linux command is commonly used to delete old files during cleanup?

The rm command is used to delete files in Linux, including on Raspberry Pi.

How can you automate data rotation and cleanup on Raspberry Pi?

You can write a script (like a Bash script) that renames or moves old files and deletes very old ones, then schedule it to run regularly using cron.

What is a simple example of a data rotation script on Raspberry Pi?

A script that renames a log file to include the date, then creates a new empty log file for fresh data, and deletes logs older than a certain number of days.

What does data rotation help prevent on a Raspberry Pi?

A Hardware overheating

B Slower internet speed

C Running out of storage space

D Screen flickering

Data rotation helps prevent running out of storage space by managing old files.

Which tool schedules scripts to run automatically on Raspberry Pi?

A cron

B nano

C ssh

D ping

cron is used to schedule tasks automatically on Linux systems like Raspberry Pi.

What command deletes files in Linux?

A rm

B mv

C cp

D ls

rm deletes files, mv moves or renames, cp copies, and ls lists files.

What is a common file renamed during data rotation?

A System files

B Log files

C Executable programs

D Configuration files

Log files are often rotated by renaming to keep recent logs separate from old ones.

Why delete old files after rotation?

A To change file permissions

B To slow down the system

C To increase file size

D To free up disk space

Deleting old files frees up disk space and keeps the system efficient.

Explain how you would set up a data rotation and cleanup process on a Raspberry Pi.

Think about how logs are handled and how to automate tasks on Linux.

Describe why data rotation and cleanup are important for Raspberry Pi projects.

Consider what happens if storage is full or cluttered.
