In Mac operating system ditto-rsrcFork command serves the purpose of copying the data. You can duplicate Mac volume and any type of file through this command like mails, documents etc. to make the backup. But this is not documented in ditto MAN pages.
A serious bug has been found with this command which can revert the chances of Mac recovery from the backups. If you use it then the resource fork seems to get copied over. But in real terms if you look at the file size of the destination version in the Finder, the resource fork does not appear there. After this launching it will not help as the resource fork will not be found.
Actually ditto -rsrcFork seems to sort of copy the resource fork over, but it must fail to convince the system that it’s bound to the file, somehow. So this is recommended that you should copy the data manually and should not apply this command. This will attach the resource fork and the metadata will remain as it is.
Relying on the ditto-rsrcFork to copy the directories and data is not recommended as this attack your data and can cause data to lose. To be sure whether the data has got lost or not, you need to check the destination folder size, to be sure that this is as big as the source. But realizing this fact after the data loss incident will be of no use. As if you want to get your data back through the copies of the data i.e. backup may not be complete.
In this case of backup incompletion, you need to have Mac recovery through the help of some third party software. A scan of the affected hard drive is required in any case of the logical data loss, which can cause due to operating system malfunctioning like incidents, which is performed by the data recovery Mac software.
Usually these Mac recovery software come tied up with the user interface which is graphically rich and hence easy to deal. According to the file system of your hard drive, you can choose the best one. But be little cautious at this stage as the wrong application may demolish your data.
