Remarks

Various

  • HInfoBackup is used to list the tasks performed or the current tasks. The scheduled tasks that have not been performed are not listed.
  • The backups performed by the HFSQL Control Center and the ones performed by programming are listed.
  • The dates and times are expressed in universal time (UTC).
Versions 23 and later

Necessary rights

To get in formation about a backup, the user or the group must have:
  • for each database affected by the backup, the rights to perform backups (hRightsBackup constant) or the rights to connect (hRightsConnection or hRightsEncryptedConnection constant).
  • for a full server backup, the rights to perform backups (hRightsBackup constant) on the server.
To find out whether these rights are granted to a user or to a group, use HInfoServerRights or HInfoDatabaseRights.
To modify the rights granted to a user or to a group of users, use HModifyServerRights or HModifyDatabaseRights.

[ + ] This educational example explains how to duplicate a database on a server.
The duplication is performed by programming and it allows you to give a new name to the database.
The example is based on the functions for saving and restoring a HFSQL backup.
