How come rsync gives different outputs when there are no files for rsync to transfer, meaning (xfr#0
) with rsync from hard disk to hard disk versus rsync from USB flash drive to hard disk?
Using:
- Ubuntu 20.04.4 LTS (Focal Fossa).
- rsync version 3.2.3 protocol version 31.
All directories are synced, up to date. Thus no files for rsync to transfer, meaning (xfr#0
) when running rsync a second time.
Example 1 script:
src1='/media/u3/d_HDD931GB/TemP'
dest='/media/u3/s_HDD931GB/1/TemP'
tput setaf 2 ; echo "$src1 $dest" ;
tput setaf 1 ; test ! -d "$src1" && echo "ErrorS" ; test ! -d "$dest" && echo "ErrorD" ; tput setaf 2 ;
time rsync -ah --delete-before --info=progress2 "$src1/" "$dest" --out-format='%t %i %C %b %n %l ' ;
echo "$src1 $dest" ; echo ;
Example 1 output:
/media/u3/d_HDD931GB/TemP /media/u3/s_HDD931GB/1/TemP
0 0% 0.00kB/s 0:00:00 (xfr#0, to-chk=0/5)
real 0m0.054s
user 0m0.004s
sys 0m0.010s
/media/u3/d_HDD931GB/TemP /media/u3/s_HDD931GB/1/TemP
The above is expected. A minimal rsync output when rsync from hard disk to hard disk and rsync has no files to transfer (xfr#0
) because hard disk is already synced.
But a long list of files with rsync output when rsync from USB flash drive to hard disk when USB flash drive has no files to transfer (xfr#0
) because USB flash drive is already synced and up to date.
Why a such a long list of files with USB flash drive?
Example 2 script, USB flash drive:
src1='/media/u3/F_4GBusb'
dest='/media/u3/d_HDD931GB/Rare/Sophos'
tput setaf 3 ; echo "$src1 $dest" ;
tput setaf 1 ; test ! -d "$src1" && echo "ErrorS" ; test ! -d "$dest" && echo "ErrorD" ; tput setaf 3 ;
time rsync -ah --delete-before --info=progress2 "$src1/" "$dest" --out-format='%t %i %C %b %n %l ' ;
echo "$src1 $dest" ; echo ;
Example 2 output, USB flash drive:
/media/u3/F_4GBusb /media/u3/d_HDD931GB/Rare/Sophos

Why does rsync give different output when there are no files for rsync to transfer, meaning (xfr#0
) with rsync from hard disk to hard disk versus rsync from USB flash drive to hard disk?
Output of sudo fdisk -l
:
Disk /dev/sdb: 3.75 GiB, 4005560320 bytes, 7823360 sectors
Disk model: Flash Disk
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x6f20736b
Output of lsblk -f
:
sdb vfat F_4GBusb
More commands --modify-window=7
did not work.
Same problem. Over 500 files listed with no rsync transfers.
2 directories are in sync, so why List 500+ files?
time rsync -ah --delete-before --modify-window=7 --info=progress2 "$src1/" "$dest" --out-format='%t %i %C %b %n %l '
Recall 2 directories are in sync. Thus no rsync transfers.
Meaning (xfr#0, to-chk=0/503)
And -c
did not work, same problem.
time rsync -ahc --delete-before --modify-window=7 --info=progress2 "$src1/" "$dest" --out-format='%t %i %C %b %n %l '
And this did not work, just -c
no --modify-window=7
.
time rsync -ahc --delete-before --info=progress2 "$src1/" "$dest" --out-format='%t %i %C %b %n %l '
rsync from hard disk to hard disk is working as expected
when `file.txt`` is deleted from destination drive.
