Hot continuous backup means that the eDirectory database is open and accessible during the
process, and you still get a complete backup that is a snapshot of the moment when the backup
began.
• Do a cold backup (the database is closed and a full backup is created)
This option is helpful when upgrading hardware or moving a server to a new machine with the
same operating system (as described in
Section 16.6, “Upgrading Hardware or Replacing a
Server,” on page 512 ).
• Set the database to stay closed and locked after a backup
• Set the maximum backup file size
To do these tasks unattended, see “Doing Unattended Backups, Using a Batch File with the eMBox
Client” on page 407 .
Prerequisites
‰ Make sure the eMBoxClient.jar file is on the machine you want to initiate the backup from.
The file is installed on your server as part of eDirectory. You can copy it from there and run it
on any machine with Sun JVM 1.1.3. You can run backups for multiple servers from a single
machine if you have access behind the firewall. For more information, see
Section 18.1, “Using
the eMBox Command Line Client,” on page 531 .
‰
If you are planning to use roll-forward logs for this server, make sure they are turned on before
a backup is made.
You must turn on roll-forward logging for servers that participate in a replica ring. If you don't,
when you try to restore from your backup files you will get errors and the database will not
open.
For more information on roll-forward logs, see
Section 14.3, “Using Roll-Forward Logs,” on
page 389 . For how to turn them on, see “Configuring Roll-Forward Logs with the eMBox
Client” on page 410 .
‰
Decide which additional files you want to back up along with eDirectory, and create an include
file if necessary.
You can back up NICI files and stream files using switches. We recommend that you always
back up NICI files.
If you want to include other files, such as the autoexec.ncf file, you must put the paths and
filenames in an include file. Separate the paths and filenames with a semicolon and don't
include hard returns or spaces. (For example,
sys:\system\autoexec.ncf;sys:\etc\hosts;
)
‰
Plan to do a file system backup shortly after doing the eDirectory backup, to place the
eDirectory backup files safely on tape. (The Backup eMTool only places them on the server.)
TIP: To make it easier to move the backup files to another storage device, you can specify the
maximum size of eDirectory backup files as part of the backup command (use -s and a number
for size in bytes). You can also use a third-party file compression tool on the files after they are
created. They compress approximately 80%.

Review the description of the command line options in “Backup and Restore Command Line
Options” on page 415 .
