Encryption Management Server backups increase in size over time. By default, the daily backup begins at 3 am. If backups become too large, the backup process cannot complete before the start of the next business day.
Encryption Management Server backups include a backup of the postgreSQL database. If the number of internal accounts on Encryption Management Server increases, so will the size of the backups.
The email messages sent to or from Web Email Protection users consume the most space in the database. The same is true of PDF Email Protection Secure Reply messages. By default, each Web Email Protection user mailbox can be up to 2 MB in size. By default, Web Email Protection messages are deleted after three months, as are users who do not logon to the Web Email Protection portal for three months.
In addition to the database, the following directories are included in the backup:
Symantec Encryption Management Server 10.5 and above.

Note that deleting records from the database will not generally reduce the disk space occupied by the database on disk but it will reduce the size of the backups.
If backup size is not an issue but the length of time taken to perform the backup is a problem, configure the backup speed to use its fastest setting by following the steps in article 203926.
