I'm performing an
rsync of files into an encrypted volume, which has a maximum size. Before performing the synchronization process I would like to determine if there is enough space left in the volume.
I have already played around with the
--dry-run option of rsync but it does not give me amount ADDITIONAL bytes that have to be transfered, e.g.
File_A -> 30KB rsync for first time change File_A -> 73KB
Now I would like to receive the amount of additional space I need, which in this case would be 43KB. That should be done for all files and sub-folders so that I can determine if the space left on the volume is sufficient.
By using the
--dry-run option like this:
rsync -an --stats test.txt folder/ Number of files: 1 (reg: 1) Number of created files: 0 Number of deleted files: 0 Number of regular files transferred: 1 Total file size: 10 bytes Total transferred file size: 10 bytes Literal data: 0 bytes Matched data: 0 bytes File list size: 0 File list generation time: 0.001 seconds File list transfer time: 0.000 seconds Total bytes sent: 68 Total bytes received: 19 sent 68 bytes received 19 bytes 174.00 bytes/sec total size is 10 speedup is 0.11 (DRY RUN)
folder/test.txt is of size 6Bytes, and the
test.txt is of size 10Bytes, therefore the difference is 4Bytes. But I only receive the total size of the file that has to be changed in the
Total file size: 10bytes.
Is there any way (or even other tool) where I can determine the additional sizes?
