Hi experts,
this is my script to Synchronize a local directory with a remote directory my problem is server HDD contain data of 79GB but local HDD of 250GB gets full. same script for other server is working i am not getting the exact problem.

#!/bin/bash

RSYNC=/usr/bin/rsync
PUBKEY=/root/.ssh/backupkey
REMOTESERVER=192.168.0.6
REMOTEPART=/mnt/disk1/
LOCALPARTITION=/backuppc_clone
emailid=adminusers@xyz.com
Dated=$(date)
sendEmail=/xyz/scripts/sendEmail.pl

RC=0
$RSYNC -r -a -v -e "ssh -i $PUBKEY -l root" --delete $REMOTESERVER:$REMOTEPART $LOCALPARTITION


RC=$?

if [ $RC -gt 0 ]
then
$sendEmail -f $emailid -t $emailid -s mail.xyz.com:25 -u "Dolphin backup failed :- $Dated" -m "Dolphin Data backup failure"
else
$sendEmail -f $emailid -t $emailid -s mail.xyz.com:25 -u "Dolphin Backup successfully Completed:- $Dated " -m "Dolphin Data backuped on Backup HDD"

--delete is the problem.
If for remote server the size of data increase by "size - X + Y"(where X is what you delete in time and Y is what you add in time) on the backup volume the size increase by "size + X" each time.
Finlay your backup volume will run out of space, how fast ? That's depend on X and Y.
Google for "snapshot like backup using rsync"

Thanks for reply

still facing overflow issue, i removed --delete string from script then also same problem.

please help me sort out this problem
