Backup Migration Failed Because of Insufficient Space

Scenarios

When you create a backup migration task, a message is displayed indicating that the space is insufficient. The following error information may be displayed:

1. The disk space of the target database is insufficient.
2. The disk space of the destination database must be 1.5 times larger than the size of the backup file.
3. The disk space of the destination database is insufficient. Check whether the backup is compressed.

Possible Causes

• The remaining space of the destination database must be greater than 1.5 times the size of the backup file.
• The backup file is compressed. As a result, the storage space of the destination database is insufficient.

Solution

Scale up the storage space by referring to Scaling up Storage Space, or contact RDS customer service to change the destination database space and perform the migration again.
