Preparing for backup and restore
Before you back up or restore data, review the preparatory
information required and the tips
recommended to ensure successful backup and restore operations. Further,
an informed backup plan
helps you recover from operational adversities with minimal turn-around.
Before you begin, verify that you meet the specified requirements
and have the requisite information to backup and restore data.
At least one of the
FTP servers recommended
The host name or
IP address of the FTP server on which you want to backup and restore data
Your FTP login user
name and password
The complete directory path on the FTP server
Maximum size of the file being backed up or restored
Various file systems and FTP server utilities have limits on the file
size they can handle. If the size of your file exceeds the file management
capacity of the file system or the FTP server utility on your server,
the file is split into multiple files before continuing with the backup
disk space on the target server to accommodate the data, otherwise the
operation will fail.
Review the tips provided in this section to pre-empt backup
and restore issues.
Schedule or perform
backups during a period of low activity.
Restoring Web sites
that reference specified Site IDs (hard-coded) onto a different control
panel server renders the site inaccessible. Do not hard-code Site IDs
in Web content. Use environment
provided by the control panel.
Using environment variables, scripts can get and use up-to-date
information without having to store that information themselves.
In addition to the standard environment variables, the following
three environment variables are available to all scripts on your site:
The root path of your site
The top level CGI path of your site
The top level HTML CGI path of your site
It is recommended that content developers use these variables
to avoid hard-coding Site IDs. This ensures that path names are always
correct, even if those path names change.
Backup and restore
of files fail on certain FTP servers. Ensim recommends the use of certain
FTP servers for successful
backup and restore operations.
Files backed up on
WEBppliance 3.0 or 3.1 are incompatible with later versions. Perform a
FULL backup of these files on the latest version of the control panel
after you upgrade from the older versions.
Backing up data using
FTP does not change the permissions of uploaded backup archives. If you
want these archives to be secure, you must modify the default FTP permissions
