Linux CLI - Networking Commands

You want to efficiently backup a large folder project/ from your local machine to a remote server daily. Which command best ensures only new or changed files transfer, compresses data, and preserves permissions?

Ascp -r project/ user@remote:/backup/project/

Bscp project/* user@remote:/backup/project/

Crsync -avz project/ user@remote:/backup/project/

Drsync -r project/ user@remote:/backup/project/

Step-by-Step Solution

Solution:

Step 1: Identify requirements
Need to transfer only new/changed files, compress data, and preserve permissions.
Step 2: Match command options
rsync -avz means archive (preserves permissions, recursive), verbose, and compress during transfer, ideal for backups.
Step 3: Compare other options
scp -r copies all files every time without compression; rsync -r lacks archive and compression flags.
Final Answer:
rsync -avz project/ user@remote:/backup/project/ -> Option C
Quick Check:
Efficient backup with compression and permissions = B [OK]

Quick Trick: Use rsync -avz for efficient, compressed, permission-preserving backups [OK]

Common Mistakes:

Using scp for large repeated backups
Omitting -a flag in rsync losing permissions
Not compressing data during transfer
