![]() b Number of files: 3 (reg: 2, dir: 1) Number of created files: 1 (reg: 1) Number of deleted files: 0 Number of regular files transferred: 1 -> Total file size: 4 bytes. Now add a new file and rsync it: echo 'b' > foo/b sending incremental file list. How can I cross check whether entire file has been transferred or just the incremental part? I tried with iptraf and iftop, but I am unable to conclude anything. This establishes that an initial rsync sends 2 bytes of data from source to target dirs. Sent 13.78M bytes received 31 bytes 27.56M bytes/sec Total transferred file size: 13.78M bytes But, It shows that, entire file was transferred: Number of files: 1 ![]() rw-r-r- 1 root root 14M Mar 10 11:15 tmpĪnd then executed the rsync command again, expecting that it would transfer only incremental part of the file. full, as its name says, loads everything, the whole source data file incremental - or delta (those are synonyms, not two different types) - mean that you load only data which you havent loaded yet. I just incremented the file size, by appending the output of seq command to the tmp file. I transferred this file to some directory using rsync as follows: rsync -avr -stats -human-readable tmp remotehost:/tmp/ ![]() Just for a test, I've created a file with details as follows: -rw-r-r- 1 root root 6.6M Mar 10 11:11 tmp whether rsync transfers entire file or just the changes made to it, when an incremental backup is fired. When doing a restore, all backups look like full backups have been performed every time: every restore point contains all files and folders of your backup source. It behaves as incremental when making a backup: only changed data is sent to the backup destination. It allows for incremental backups, update whole directory tree and file system, both local and remote backups, preserve file permissions, ownership, links. I need to test the incremental backup of a file using rsync i.e. Duplicati combines the advantages of all backup methods.
