17.2.2 What's Different between Backup and Restore in DSBK
and TSA for NDS Backup
In previous versions of eDirectory, backup and restore was focused on backing up the tree, object by
object.
The Backup Tool in eDirectory 8.7 introduced a completely new focus and new architecture. It's
server-centric, not tree-centric; you back up the eDirectory database on each server individually. It's
much faster than the legacy TSA for NDS backup.
The legacy TSA for NDS backup tool can still be used to back up the tree, although we encourage
you to use the new backup.
For more comparison information, see the following table.
Issue
Legacy TSA for NDS Backup
Backup Tool “Hot Continuous Backup”
Focus
Designed to back up the tree,
object by object.
For more information about the
legacy backup utilities (that still
work in 8.7 - both kinds of backup
can be used if necessary), see
“Backing Up and Restoring Novell
eDirectory” (http://www.novell.com/
documentation/lg/ndsedir86/
taoenu/data/a2n4mb6.html)
in the
Novell eDirectory 8.6
Administration Guide
.
Designed to back up the eDirectory
database on each server individually.
Fault tolerance for the whole tree should be
provided primarily by replication, but backing
up each server provides additional fault
tolerance.
When planning a restore strategy for the tree
after a disaster in which many servers are
lost, consider using DSMASTER servers and
replica planning as outlined in
“Using
DSMASTER Servers as Part of Disaster
Recovery Planning” on page 433
.
Speed
N/A
Significantly improved. Speed is one of the
most important features of the new backup.
Where the backup
is placed
Allows backup to be placed directly
to tape.
Places the backup files on the file system.
You must use a file system backup to put
them on tape for safe storage.
Cross-platform
Performs differently on each
platform.
Works the same way on each platform.
Ability to restore
individual servers
Not designed to provide this.
Provides the ability to restore an individual
server after a hard drive failure or to use
backup to move a server from one machine
to another.
Provides the option to use roll-forward
logging so you can restore a server to the
state it was in at the moment before it went
down, so it is in the synchronization state
expected by other servers in a replica ring.
Has the ability to back up files related to
eDirectory on an individual server. For
example, you can back up and restore NICI
files. You can also create your own list of
related files to include with the backup.
