Back-up log file

[Guest Vriendje]

Hi,

 

Every night i use a bash scritpt to backup up my files form Drive A to Drive B.

Also there will be created a log file.

In this log file i like to see some info about a directory.

 

For example:

 

I start this command before the backup on my Freenas 7.x

echo " Web - Files :`find $SOURCE_WEB_F -type f | wc -l`" " /`find $DEST_WEB_F -type f |wc -l`" >>$LOG

After the backup i run this line again so i can see that all the files are on the backup disk

 

So what i like is the info after the backup in one line

 

Backup files - Source files - Files after backup

web 200 300 300

 

I like it this way but how can i see this info in one line after the backup (in the log file) :unsure: ??

Thanks for helping.

I’m not sure I understand. Given the knowledge you seem to have with scripting, what I’m going to write somehow seems too simple…

So you have a script that is responsible for the backup, and you execute the same command at the start and at the end of the backup. The first occurrence gives “S0/D0â€, and the second gives “S1/D1â€, and you’d prefer instead “D0 S1 D1†on one line at the end. The logical way, in my opinion, would be to store D0 in a variable and then print everything at the end, like this (I assume bash as the shell):

D0=$(find "$DEST_WEB_F" -type f -print | wc -l)
… do the backup …
printf 'Backup files - Source files - Files after backup\nweb %d - %d - %d\n' \
 $D0 \
 $(find "$SOURCE_WEB_F" -type f -print | wc -l) \
 $(find "$DEST_WEB_F" -type f -print | wc -l) >>"$LOG"

By the way, if you have a lot of files, “find … -printf . | wc -L†is slightly more efficient than “find … -print | wc -lâ€

Thanx theYinYeti

 

I'm not that good with scripting. I know it has something to do with the DO command but i never used it.

So this was complete new for me. I can read it and i understand, but i never knew how to make one by myself:-)

 

Thanx, I think this is what i'm looking for.

 

I also will try -printf command.

Update:

 

Still have a little problem

 

I have more directories to check before and after the backup.

 

------

echo " Workstation - Files :`find $SOURCE_WRKST_F -type f | wc -l`" " /`find $DEST_WRKST_F -type f |wc -l`" >>$LOG

echo " Shared - Files :`find $SOURCE_SHARED_F -type f | wc -l`" " /`find $DEST_SHARED_F -type f |wc -l`" >>$LOG

echo " Web - Files :`find $SOURCE_WEB_F -type f | wc -l`" " /`find $DEST_WEB_F -type f |wc -l`" >>$LOG

echo " Pictures - Files :`find $SOURCE_PIC_F -type f | wc -l`" " /`find $DEST_PIC_F -type f |wc -l`" >>$LOG

echo " Movies - Files :`find $SOURCE_MOVIES_F -type f | wc -l`" " /`find $DEST_MOVIES_F -type f |wc -l`" >>$LOG

------

 

How can i check this before and after the backup with a do command?

 

btw when i start the script you wrote i see a zero?

 

web 756 - 756 - 0 <- It looks like he does not start the $(find "$SOURCE_WEB_F" -type f -print | wc -l) \

Even if change it to DEST_WEB_F it still returns a 0

 

Thanx for helping again!

Vriendje, there is no DO command :-) I wrote D0 (dee zero, which stood for Destination at time T0), which is a variable, inside of which is stored (“=â€) a value which is the result of a command (“$(…)†notation is equivalent to the “`…`†notation but can be nested).

 

To do what you asked, you would write your script like this:

for d in WRKST SHARED WEB PIC MOVIES; do
   eval D0_$d=$(find "$DEST_${d}_F" -type f -printf . | wc -L)
done

… do the backup …

printf '\tBackup files\tSource files\tFiles after backup\n' >>"$LOG"
for d in WRKST SHARED WEB PIC MOVIES; do
   eval printf '%s\t%d\t%d\t%d\n' \
       \$D0_$d \
       $(find "$SOURCE_${d}_F" -type f -printf . | wc -L) \
       $(find "$DEST_${d}_F" -type f -printf . | wc -L) >>"$LOG"
done
