526 Backup and restore
If the user declines the confirmation, the Element Manager browser returns
to the backup schedules page.
Note that when the backup schedules configuration page is loaded as a
result of the user selecting the Add button on the backup schedules page,
both the Refresh and Delete buttons are disabled.
Element Manager ensures the information in this page is kept current by
querying the call server for the requested backup schedule data and the
currently configured backup rules.
Backup scheduler
Backup operations can be scheduled to run automatically at user-defined
intervals to user-defined destinations (such as external FTP servers or
removable CF cards). This is done by defining Backup Schedules in LD 117.
The following conditions apply:
• For each schedule, the frequency (monthly, weekly, daily or automatically
after every EDD) must be defined along with the day and time of the
activation. A maximum of ten schedules can be defined.
• For each schedule, a backup rule must be used. It can be any rule type:
FTP, FMD, RMD, or SCS.
This feature is not applicable to the Secondary Call Server of the Geographic
Redundancy feature.
Backup and restore maintenance
Corrupted backup data
Backup data is protected in the following ways:
• Traditional protection in the form of an archive.dat file, including the list
and checksum of the files backed up.
• The new backup operation, which "envelopes" the backup data by using
tar and gzip utilities to provide additional checksum protection.
If backup data is corrupted, the restore operation is aborted and the proper
alarm report is generated.
FTP data transfer failure
The FTP client facility is used to access a remote FTP server for the
following operations:
• manual or scheduled backup
• restore according to backup rule (manual activation only)
