Ok, thanks for that additional info.

However, looking at the script, I'm thinking this should definitely work, but for some reason, nothing is ever getting copied into the backup directory. It creates the backup directory, but nothing is ever placed into it.

Here is the code I'm running:

Code:
#
# FILESERVER INCREMENTAL BACKUP SCRIPT
#

# Remove previous log file

rm /usr/local/bin/rsync-incremental.log

# Set variables

BACKUPDIR=`date +%A`
SRC="/usr/smbshares/"
TRG="root@synology1:/volume1/Fileserver/Current/"
OPT="-avhz -e ssh --log-file=/usr/local/bin/rsync-incremental.log --delete --backup --backup-dir=$BACKUPDIR"

echo BACKUPDIR > /usr/local/bin/rsync-incremental.log
echo $BACKUPDIR >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log

# Remove old backups

rsync --delete -a /usr/local/bin/emptydir/ root@synology1:/volume1/Fileserver/$BACKUPDIR

echo SOURCE >> /usr/local/bin/rsync-incremental.log
echo $SRC >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log
echo TARGET >> /usr/local/bin/rsync-incremental.log
echo $TRG >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log
echo OPT >> /usr/local/bin/rsync-incremental.log
echo $OPT >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log

# Perform the rsync

rsync $OPT $SRC $TRG

Here is the top of the rsync-incremental.log file with the variables spelled out:

BACKUPDIR
Tuesday
------------------
SOURCE
/usr/smbshares/
------------------
TARGET
root@synology1:/volume1/Fileserver/Current/
------------------
OPT
-avhz -e ssh --log-file=/usr/local/bin/rsync-incremental.log --delete --backup --backup-dir=Tuesday
------------------


So the rsync line passed is:

Code:
rsync -avhz -e ssh --log-file=/usr/local/bin/rsync-incremental.log --delete --backup --backup-dir=Tuesday /usr/smbshares/ root@synology1:/volume1/Fileserver/Current/

But, as I said, nothing is ever copied into the Tuesday folder! It is created, but nothing is under it. Also, there are definite changes made to SEVERAL HUNDRED files per day under /usr/smbshares, I can assure you.

Now, to test, I took one of the subdirectories under /usr/smbshares and typed the following line:

Code:
rsync -avhz -e ssh --delete --backup --backup-dir=darrellpbackup /usr/smbshares/darrellp root@synology1:/volume1/Fileserver/

I then went and made a small change to one of the files and performed again and it backed up the previous copy of the file in the backup folder!

Can you guys see anything I'm missing here?

Ok, I've figured this out somewhat.

It is creating a folder under /volume1/Fileserver/Tuesday, but it is ALSO creating a folder under /volume1/Fileserver/Current/Tuesday.

The second is where the backups are being placed, but the first is the empty (and that's where I've been looking for the backup files).

Any idea based on the rsync command why it would create the 1st folder?

Thanks!

Ok, after fiddling some more, I've changed my code to:

Code:
#
# FILESERVER INCREMENTAL BACKUP SCRIPT
#

# Remove previous log file

rm /usr/local/bin/rsync-incremental.log

# Set variables

BACKUPDIR=`date +%A`
SRC="/usr/smbshares/"
TRG="root@synology1:/volume1/Fileserver/Current/"
OPT="-avhz -e ssh --log-file=/usr/local/bin/rsync-incremental.log --delete --backup --backup-dir=/volume1/Fileserver/$BACKUPDIR"

echo BACKUPDIR > /usr/local/bin/rsync-incremental.log
echo $BACKUPDIR >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log

# Remove old backups

rsync --delete -a /usr/local/bin/emptydir/ root@synology1:/volume1/Fileserver/$BACKUPDIR

echo SOURCE >> /usr/local/bin/rsync-incremental.log
echo $SRC >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log
echo TARGET >> /usr/local/bin/rsync-incremental.log
echo $TRG >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log
echo OPT >> /usr/local/bin/rsync-incremental.log
echo $OPT >> /usr/local/bin/rsync-incremental.log
echo ------------------ >> /usr/local/bin/rsync-incremental.log

# Perform the rsync

rsync $OPT $SRC $TRG

Seems to be working so far and will let you know after a day or two to make sure things are being backed up to the appropriate folder. What was happening is the "Clear" rsync was going to one folder where the "Backup" rsync was going to the other one. By specifying the "Backup" folder including the path, they now point to the same folder. Just wasn't sure if that would work via the rsync since I was specifying a path on the remote server, but seems to like it!
