Verify and changed files
The view is depended upon selecting a row in Execute view. When the view is selected the numbers of source and remote destination are automatically collected.
--archive parameter is the normal parameter to use in synchronize and snapshot tasks because it is fast. The
--archive parameter to rsync preserves a lot of attributes of files when synchronizing. Files transferred in
--archive mode ensures that symbolic links, devices, permissions, ownerships, modification times, ACLs, and extended attributes are preserved. When synchronizing files based upon the
--archive parameter, rsync compares file size and last modification time to compute which files to be synchronized.
--checksum parameters forces rsync to evaluate files based upon 128-bit MD5 checksum. Rsync computes and compares the checksum of all files. Files with not equal checksum are listed. This is a more time consuming task because rsync computes and compare the checksum for every file and it is therefore best for verifying a backup.
Warning: RsyncOSX does not evaluate the result from neither a verify or changed function. The user has to evaluate the result self and take required actions.
Verify button kicks off the
--checksum process. The output is appended and refreshed every time rsync output a new line.
Changed button kicks of a
--dry-run restore task. Changed and deleted files in source compared to last synchronizing or snapshot task are listed. This process is utilizing the
--archive parameter. For both functions the corresponding rsync command is presented.
If the verify finds files not synchronized a
touch command on file will update timestamp on file and next synchronize task will copy missing files.
Below is sample of verify for standard synchronizing task. Seven files are verified as not equal. The seven files are also identified by the normal backup task.
The result of a synchronizing task.
Below is sample of verify for snapshot synchronizing task. The source and backup is identical after the synchronizing task.
A verify is probably best to to do after a synchronizing is completed. If there are any files which checksums are not equal, rsync list those files. In the view above all checksums are equal and backup is verified equal to source.
For snapshot tasks the synchronize and verify rsync command is slightly different.
