Thanks I already got it back its just logged in my desktop so I didn't pay attention when replying.

@Diantre: Correct. http://www.mikerubel.org/computers/rsync_snapshots/ has inspired me.

@jheengut: I like to enclose my scripts in pushd/popd to ensure that they start in a predictable directory and they return to the previous location when finished. Most of the times it is not strictly required, it's just a habbit of mine.

@moisespedro: rsync, does not compress files for storage, it does compress them during transfer.

incremental daily backup
 

I use this lines in cron.daily script:

/usr/bin/rsync --delete-excluded --backup --backup-dir=snapshots/$(date +%Y%m%d) -a /home

If it works for you, then it is fine, just don't call it "incremental" because it isn't.
It is a full backup.

A single full backup is a true copy of the latest amendment is created. The "snapshots" directory contains various files of past backups.

Please see du -sh on backup dir.

Let me state again, that if it works for you it is fine, but I still insist that you are not performing an incremental backup.

https://en.wikipedia.org/wiki/Incremental_backup
"...An incremental backup is one that provides a backup of files that have changed or are new since the last incremental backup;[1] it is one that backs up only the data that changed since the last backup — be it a full or incremental backup..."

The rsync command you have stated, does a full copy of the /home directory, it does not copy only changes files since the last backup. Hence, it is not an incremental backup, rather a full backup of the /home directory.

But, lets leave it at this. You are obviously happy with your backup scheme, so there is no point in this conversation.
