210 - Ist es möglich, die Dateien mit ISP verschlüsselt abzulegen oder zu übertragen?

Yes, you can back up encrypted files using ISP. However, encryption must first be configured on the ISP client.
Bear in mind that without the encryption password, it is no longer possible to restore the encrypted data. 

Setting up encryption

Setting up SP encryption consists of three steps:

1. Allow encryption in client option file dsm.opt (Windows) and in client system option file dsm.sys (Linux). Two lines must be inserted for this:

   encryptkey <keytype>
   ENCRYPTIONTYPE <type>

   Keytype has one of the values prompt, save or generate.
   save only applies when using passwordaccess generate and is required when using ISP schedules.
   Type has one of the values AES256, AES128 or DES56.
   Example:

   passwordaccess generate
   encryptkey save
   ENCRYPTIONTYPE AES128

2. Insert the specification for the objects to be encrypted in the inclexcl file. This can be done using include.encrypt <specification> entries. Example:

   include.encrypt /tmp/Encrypt/*

3. Start the ISP client and back up a file from one of the directories to be encrypted. During the first encrypted backup, ISP will request the encryption password and store it in encrypted form in the file TSM.PWD.

Checking the encryption

Via the command line:

dsmc query backup <file specification> -subdir=yes -detail

Example:

dsmc query backup /tmp/Encrypt/d -detail

Detailed information about the file is output:

Größe Sicher.-Datum Verw.klasse A/I Datei

You can see in the penultimate line that the encryption type (= Verschlüsselungstyp: 128-Bit-AES) is active.

Here you can see that no encryption type has been set (= Verschlüsselungstyp: Keine) and that the file has not been encrypted accordingly.

Graphical client:

Select a file that you have backed up in encrypted form. Right-click to open “File information” from the menu. Among other things, the encryption type is displayed: Encryption type: 128-bit AES (= Verschlüsselungstyp: 128-Bit-AES)
If the above setup was not successful, ISP shows that no encryption type has been set by displaying Encryption type: NONE (= Verschlüsselungstyp: Keine).
