cp wont copy new files

[mstrauss2023]

I have a cronjob that runs a bash file called mountnas.sh (it used to mount but I made the mount permanent - now it just copies)
mountnas.sh
#!/usr/bin/sh
cp -ufr /mnt/nas/Share_MC /home/mike/backup/nas/
-ufr = copy files that are updated, recurrsive and force

cronjob:
52 12 * * * /home/mike/backup/mountnas.sh > /home/mike/backup/mountnaserrorlog.txt 2>&1


it copies all files and sub folders from a NAS drive to /home/mike/backup/nas/
when i first ran it it copied everything.
Then I added a new file to it called 0.mike test2
then i rescheduled the cronjob but 0.mike test2 doesnt copy

mountnaserrorlog.txt gets created but is blank

Any help would be appreciated

I haven't gotten any replies so I decided to play with rsync and found that to be a better solution.

MY solution:

Code: Select all

30 18 * * * rsync -vrulEogt --delete /mnt/nas/Share_MC /home/mike/backup/nas

The flags:
v = verbose (increase verbosity)
r = recursive (recurse into directories)
u = update (skip files that are newer on the receiver)
l = links (copy symlinks as symlinks)
E = executability (preserve executability)
o = owner (preserve owner (super-user only))
g = group (preserve group)
t = times (preserve modification times)
delete = delete extraneous files from dest dirs

-a option includes
-r
-l ( lower case L )
and -o.... options

Thus you could simplify that part as

-avuE

-H preserves hard-links...( which I don't recall if you needed that too or not)
-h makes it more " human readable "
... aka ...Output numbers in a more human-readable format. This makes big numbers output using larger units, with a K, M, or G suffix. If this option was specified once, these units are K (1000), M (1000*1000), and G (1000*1000*1000); if the option is repeated, the units are powers of 1024 instead of 1000.
