scp shows size variation
Hi

i have folder of 26 GB on server A and want to copy to server B .i used the below commands to check file size and scp copy
Code:
du -h /folder :  its shows 26G on server A

from server B:
Code:
scp -r user@serverA:/folder/* ./

copying got initiated and i am checking the file size on server B using

Code:
du -h /folder :  now its shows 33G : still copying is going...dont know when it stops

my question is why there is size variation ?

Do you have any symbolic links underneath /folder? Or sparse files?

You might want to consider using rsync to copy the files.

-r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.

Sounds good if your user is allowed to create such large files and if the file system is capable of such large files.

Why not transfer in one go ? especially if you have links...
Can you use .rhosts during your copy?

after verification i found that m.d.ludwig is right , all the symbolic links were copying as normal files it increased my space

i have added the keys in .ssh/known_hosts , can you please tell me about .rhosts or direct me the location to read more about .
