Is there a way of preserving the timestamp when using Paramiko to SFTP files from one server to another similar to the -p argument in Linux?
Original file:
jim@vm3634:~$ ls -la
-rwxrwx--- 1 jim admin 2214 Mar 30 17:33 compcip.asc
Uploaded file:
sftp> ls -la
-rwxrwx--- 1 no-user no-group 2214 Mar 30 18:49 compcip.asc
The uploaded file needs to have the same timestamp as the original.
回答1:
Paramiko does not support that.
You have to explicitly call the SFTPClient.utime after the upload.
Note that pysftp (that internally uses Paramiko) supports preserving the timestamp with its pysftp.Connection.put() method.
You can reuse their implementation (code simplified by me):
local_stat = os.stat(localpath)
times = (local_stat.st_atime, local_stat.st_mtime)
sftp.put(localpath, remotepath)
sftp.utime(remotepath, times)
Similarly for downloads.
