Command to perform Full and Differential backups
 

Hey Guys,

I have searched the net and found a few ideas/solutions to perform full backups using the TAR utility. I would like to perform a weekly full backup (Saturdays) and daily differential backups (Su-Fri) for a folder located on a Ubuntu server.

So far I have tried:

but this duplicates the folders on the tar file

I also tried:

and it seems to create a new one tar

Server: Ubuntu Server 16.04

Thank you

tar can be used to create an incremental backup using the --listed-incremental option. If the snapshot file does not exist or if you use the --level=0 option then a full backup (level 0) is performed otherwise it is a level 1 backup.

Always verify your backups...

Thank you. I will read the documentation on the link below, test and verify my backups.

You will likely be better served to use rsync, take a look at it's man page - it is what most back up programs use. :)

Also, look into cron to do the work for you.

+1 for rsync -- and rsnapshot to control and manage it with minimum effort.

Thank you guys for your responses! After testing different scenarios I will use Rsync for incremental backups and tar for weekly full backups. Thank you so much!
