    Hey there! The best thing to do would be to examine the size of the specific backup directories being created. The following command will show you everything inside the /backup directory: du -h --max-depth 1 /backup
    Can you check that to determine where most of the usage is?

    Hello result below command du -h --max-depth 1 /backup 1.7T ./weekly 493M ./.meta 16K ./lost+found I have already checked it. My question is Server main hard drive usage 1310 GB but incremental backup usages 1665 GB. As i have only one backup so how their is too much difference around 355 GB excess usage at incremental backup.

    Thanks for that - now that you have that information, you can run the command again on the "weekly" directory: cd /backup du -h --max-depth 1 weekly
    and you'll see the disk usage of things inside that directory. You'll keep digging deeper with this process until you find individual files, or in your case, directories since you are using the incremental option, that show the disk space.

    Hello I have done all. May i am unable to clarify you. last day again i have delete all backup and regenerate backup again after that i found the discrepancy again. A single example [root@ssd2]# du -sh /backup/weekly/2022-01-27/accounts/crowncem/homedir/mail/ 571G /backup/weekly/2022-01-27/accounts/crowncem/homedir/mail/ [root@ssd2]# du -sh /home/crowncem/mail/ 419G /home/crowncem/mail/ I question is why the difference about 152 GB with server main data and incremental backup data ??? After backup data might be enlarge.

    Incremental backups backup all the changes that have been made since the previous backup was taken, although that does seem like a large amount of email. It might be best to open a ticket with our support team so we could examine the system directly and get you more information.
