I used 2 commands
tar to perform the same operation of backing up data to an external drive which is my 8Gb pen drive (sandisk brand). At the time of executing the commands, it outputs something implying that it has backed up something but when I check the media, it is blank.
ravi@ravi-Aspire-5315:~/Documents/testing$ find . -type f -newer .last_time ./jill1 ravi@ravi-Aspire-5315:~/Documents/testing$ find . -type f -newer .last_time | cpio -o > /dev/sdb2 1 block ravi@ravi-Aspire-5315:~/Documents/testing$
Now please look at the backed up media.
ravi@ravi-Aspire-5315:/media/ravi$ df -h | grep sdb2 /dev/sdb2 3.9G 8.0M 3.7G 1% /media/ravi ravi@ravi-Aspire-5315:/media/ravi$ ll total 24 drwxr-xr-x 3 ravi ravi 4096 Jan 12 11:10 ./ drwxr-xr-x 3 root root 4096 Nov 20 13:51 ../ drwx------ 2 root root 16384 Jan 12 11:10 lost+found/
I tried many times by backing up all files also but noting is shown in the above directory
/media/ravi which is mount point of
I tried the
tar command but the same issue.
ravi@ravi-Aspire-5315:~/Documents/testing$ tar -cvf /dev/sdb2 `find . -type f -newer .last_time` ./jill1
Here it is mentioning that the mount point is
df -h mentions a different mount point
ravi@ravi-Aspire-5315:~/Documents/testing$ df -h | grep sdb /dev/sdb2 3.0T 3.0T 3.9G 100% /media/ravi
The size is also wrongly shown now as 3.0T though it is 3.9 GB as shown in the command output in the beginning of this thread.
The above is what I found in my pendrive.
Before using this media, I 1st tried in an SD card of 32 GB. There also the issue was coming. So, I felt that the issue is with the SD card as I suspected the ingenuity of that card. But after using my branded 8GB pendrive (sandisk brand) bought from amazon.in, I am confirmed that the problem is something else.
