Full backup:

Establish test paths and files

mkdir Test Touch Test/{a,b,c}

Generate three files under test

Perform a full backup

tar -G snapshot-zcf backup_full. tar. GZ test

View Tarball Content

tar ztf backup_full. Tar . Gztest/Test/atest/btest/C

Differential + Incremental Backup:

Add a file and modify the contents of a file

Touch test/eecho123 > test/a

Perform a second incremental backup (note tarball file name)

tar -G snapshot-zcf backup_incremental_2. tar. GZ test

View Tarball Content

tar ztf backup_incremental_2. Tar . Gztest/Test/atest/E

Restore Backup data:

Clear test data

RM -RF Test

Start a data restore

tar zxf backup_full. Tar . GZ tar zxf backup_incremental_1. Tar . GZ tar zxf backup_incremental_2. tar. gz

View Test Data

ls Testa b c D e
