# VBS Backup Management

You can set filtering criteria to query wanted backups, add tags to backups for grouped management, and share your backups with other projects.

CSBS backups of ECSs are also displayed on the VBS backup page and can be distinguished from VBS backups by Source in the backup details.

After Instant Restore is enabled, each backup will be marked with a letter C or E at the right of its name to show whether it supports instant restoration. A backup marked with letter C is a common backup and does not support instant restoration. A backup marked with letter E is an enhanced backup and supports instant restoration. For details, see Instant Restore.
