arc

--arc=<archive name>

Name of the archive. Parameter values are case-sensitive.

Using variables in archive names

When you back up more than one machine with a single backup command, data from all of the machines is saved to the same location. Each machine backs up to a separate archive. Archive names must be unique within the location. Otherwise, the backup operation will fail.

Add variables to the archive names to make them unique within the location. For the backup vm command, the archive name must contain the [Virtualization Server Type] and [Virtual Machine Name] variables. For other backup commands, use the [MachineName] variable.

You can also use these variables when backing up a single machine if this is practical or efficient for you.

Examples:

--arc="[Virtualization Server Type]_[Virtual Machine Name]_archive1" – for the backup vm command
--arc=[MachineName]_archive1 – for the backup disk and backup file commands

Specifying archives by backup file names

In this parameter, you can specify an archive by the file name of a backup that belongs to the archive; for example: --arc=my_backup2.tib.

If the archive does not contain metadata, the command will apply to the backup chain. (A backup chain is a full backup and all of its dependent incremental and differential backups.)

This syntax is useful for archives created using the --plain_archive parameter. Also, this syntax is the only way to access an archive if its metadata has not been created or is lost for some reason.

If you need to use the --backup parameter with the command, specify a backup identifier rather than a file name as this parameter value. For example:
Correct
--arc=my_backup2.tib --backup=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
Incorrect
--arc=my_backup2.tib --backup=my_backup3.tib

Restriction: You cannot specify file names of backups stored on Acronis Storage Node, Acronis Online Backup Storage, Acronis Secure Zone or tape.
