Download Files From SFTP Server That Are Older Than 5 Days Using Python

I got a Python script on this site that downloads files from the directory from SFTP server. Now I need help to modify this code so that it only downloads the files that older tha

Solution 1:

Use the pysftp.Connection.listdir_attr to get file listing with attributes (including the file timestamp).

Then, iterate the list and pick only the files you want.

import time
from stat import S_ISDIR, S_ISREG

def get_r_portable(sftp, remotedir, localdir, preserve_mtime=False):
    for entry in sftp.listdir_attr(remotedir):
        remotepath = remotedir + "/" + entry.filename
        localpath = os.path.join(localdir, entry.filename)
        mode = entry.st_mode
        if S_ISDIR(mode):
            try:
                os.mkdir(localpath)
            except OSError:     
                pass
            get_r_portable(sftp, remotepath, localpath, preserve_mtime)
        elif S_ISREG(mode):
            if (time.time() - entry.st_mtime) // (24 * 3600) >= 5:
                sftp.get(remotepath, localpath, preserve_mtime=preserve_mtime)

Though the code can be much simpler, if you do not need a recursive download:

for entry in sftp.listdir_attr(remotedir):
    mode = entry.st_mode
    if S_ISREG(mode) and ((time.time() - entry.st_mtime) // (24 * 3600) >= 5):
       remotepath = remotedir + "/" + entry.filename
       localpath = os.path.join(localdir, entry.filename)
       sftp.get(remotepath, localpath, preserve_mtime=True)

Based on:

• Python pysftp get_r from Linux works fine on Linux but not on Windows
  (I have updated this source of your code to use listdir_attr as it's more effective)
• How to sync only the changed files from the remote directory using pysftp?
• Delete files that are older than 7 days
