Datensicherung

Rolf, are you changing backup or file names inbetween doing these backups?  If so, this may be why you are seeing a full backup each time and not getting a differential backup.

As I test, I would suggest creating a new backup task selecting the differential scheme - run the backup to create an initial full backup, then run the backup again perhaps an hour or two later, when you have used the system normally inbetween, then check to see if you have now created a differential backup.  Note: do not make any changes to the backup task after you create it, nor any changes to the folder or image file where you store the backup.

Wenn ich ein Vollbackup mache vergebe ich einen Dateinamen: z.B.: Sicherung LW C am 20.02.2016. Wenn ich jetzt das differntielle Backup machen will, welchen Namen muss ich dann vergeben? Denselben wie vorher (Sicherung LW C am 20.02.2016) oder einen anderen?

Danke

P.S. Ich verstehe Englisch, kann aber schlecht schreiben.

Hello Rolf, you do not need to give a name when creating a differential backup - you simply choose the backup scheme that you want to use and then ATIH will create an initial full backup then will create differential backups based on that first full backup and append text to show what type of image has been created.

See my screen capture attached which shows the full and differential images on one of my systems where the backup name is 8cdrive and where ATIH has added _full and _diff to the image file names as it creates a weekly differential backup.

You may want to read through the guides that Grover has posted on the topic of backups.

See https://forum.acronis.com/forum/75086 and http://forum.acronis.com/forum/100416 which give a comprehensive explanation of the different types of backup you can configure and how they work.

Hallo Steve,

weiß nicht mehr weiter.  Habe folgendes gemacht:

1. Neues Backup erstellen gewählt, habe dann unter Optionen eingegeben: siehe Anhang 1. Datensicherung.

2. Habe dann LW C verändert (Daten gelöscht und neue Dokumente erstellt - also Veränderung)

3. Habe dann wieder neues Backup erstellen gewählt mit Einstellungen 2. Datensicherung (keine Änderung des Dateinamnes).

Ergebnis: wieder VollBackup mit Veränderungen und verändertem Dateinamen (Endung hat sich verändert - Dateiname ist beibehalten). Sicherung dauert genau so lange wie vorher und hat keine "kleine neue Datei" erstellt - also nur die Veränderungen speichern. Was mache ich falsch? Sind die Einstellungen nicht korrekt?

Hello Rolf, I think that I understand what you are doing here, but let me set it out to confirm if I understand you correctly!

You are creating an intitial full backup; you made some changes in your system; you then create a new Backup task with the same name as the initial full backup and this created a further new full backup image and not a differential one?

In your document, you show that you have chosen to use a Custom Scheme using the Differential Backup Method and then to only create Differential backup images after the initial full backup is created.

That is all that is needed.  The backup task should create the full backup and then only create differential backups after that, there is nothing more that you should need to do.  There is no need to create any other tasks.  This one Custom backup task will create both types of backup, i.e. one full backup, and then multiple differential backups (one for each time the task is executed either by schedule or manually).

Hallo Steve,

vielen Dank für die sehr schnelle Antwort!!! Genau so wie du es geschrieben hast habe ich es gemeint: 1 Vollbackup, dann nur noch differntielle Backups (sind ja wesentlich kleiner und schneller beim Speichern).

Kannst du mir bitte ein paar screenshots von diesen Einstellungen machen und mir zuschicken, damit ich ganz sicher bin. Vielen Dank.

In der Hoffnung, dass dann alles funktioniert, verbleibe ich

Rolf, there is a comprehensive guide with examples that Grover posted at https://forum.acronis.com/forum/100416 which included doing a Custom Scheme with Differential backups.

The attached PDF document shows the configuration from one of my Windows 10 systems which uses the same Custom scheme with Differential backups performed once a week.

Hallo Steve,

habe alles so eingestellt wie beschrieben. Kein Erfolg immer nur Vollbackups, obwohl der Dateiname sich ändert mit den Zahlen 1 - 5 am Ende. An der Größe kann man schon erkennen, dass es ein Vollbackup ist. In der Anlage übersende ich noch einmal meine Einstellungen von Anfang bis Ende wie ich die Backups durchgeführt habe. Ist etwas falsch?

Wenn ich keine Lösung habe, werde ich nur noch Vollbackups machen, da ich auf den externen Festplatten genug Speicherkapazität habe. Schon jetzt erst einmal vielen Dank für deine Mühe.

Rolf

Hello Rolf, everything in your settings looks good and should work correctly to produce differential backups!

I set up a new backup myself this morning with the same settings and that worked just fine.

At this point there are several options that you can consider:

1.  To try setting up a new backup job with the exact same settings for Custom Scheme & Differential backups, but ensure that you use a new task name and put the backup into a new (never used before) target folder on your storage drive.  This should help eliminate if ATIH 2015 is finding information in the configuration database that is being reused in error.

2.  If option 1 does not work and still produces only full backup images, then my recommendation would be to uninstall ATIH 2015, run the Acronis Cleanup tool (see in my signature below for the link), then perform a clean install, downloading a fresh copy of the installation program from your Acronis Account.  This will give you a clean start but will mean having to recreate all of your backup tasks again, so you will want to make a note of how these are set up before starting on this step.

3.  The third option is to do nothing and live with the way ATIH 2015 is working at present in creating only full backups.

4.  A further option is to try using the alternative Differential settings (not selecting to only create differential backups after the initial full backup) where you select to create say 30 differential backups then create a new full backup, plus set up the automatic cleanup rules to help protect the space all these backups will take on your storage drive.

Hallo Steve,

habe folgendes gemacht.

1. Differentielle Sicherung mit neuem Dateinamen und einem anderen Zielverzeichnis --> kein Erfolg, wieder Vollbackup

2. Inkrementelle Sicherung mit neuem Namen und neuem Zielverzeichnis --> kein Erfolg, wieder Vollbackup

3. ATI volkommen deinstalliert. ATI neu installiert und Punkt 1 und 2 durchgeführt. --> kein Erfolg, wieder Vollbackup

Werde jetzt nur noch Vollbackups machen.  Hat sonst keinen Erfolg. Bedanke mich für die sehr gute Hilfe, die aber leider zu keinem Erfolg geführt hat.

Rolf

Hello Steve,
did the following.
1. Differential backup with a new file name and a different target directory -> no success, 
again full backup
2. Incremental backup with a new name and target directory -> no success, again full backup
3. ATI Completely restructured uninstalled. ATI reinstalled and performed point. 1 and 2 -> 
No success, again full backup
Become now only make full backups. Has anyone not succeed. Thank you for the very good help, 
which has unfortunately proved fruitless.
Rolf

Hello Rolf, thank you for your patience in this matter and for trying my suggestions to try to resolve it.

I have to confess that I am puzzled that you are still seeing only full backups despite uninstalling, cleaning and reinstalling ATIH 2015 and using new file names and target directories.

Can I ask you to do one more test for me please?

Can you collect the logs from the C:\ProgramData\Acronis\TrueImageHome\Logs folder and put these in a zip file and attach them to your next post in the forum so that I can see what messages are shown for your attempts to create either incremental or differential backups.

If it would be easier for you to identify the log files, then please clear the folder first (either delete or move the contents to a temporary folder) and then repeat the backup test, then collect the new logs that are generated for the same.
Note: please ensure that if you are creating a new backup task that you run that task twice, the first time will always create a full backup, but the second and subsequent times should produce an incremental or differential backup depending on what you have configured.

Hallo Steve,

bei der Neuinstallation gab es Probleme. Kam immer Fehlermeldung (sehr lang, Windows). Kann ich jetzt nicht reproduzieren. Sonst muss ich wieder deinstallieren und erneut versuchen zu installieren, um die Fehlermeldung zu erhalten. Habe deshalb die letzte Vollbackup Version zurückgespielt. Würde dir gerne die log Datei schicken, aber wo finde ich diese? Habe Bild vom Explorer mitgeschickt. Den Ordner: C:\ProgramData\Acronis\TrueImageHome\ finde ich nicht. Wie heißt die Datei genau? Welche Dateiendung? Wo ist der Ordner (im Explorer habe ich bei Ansicht angeklickt, dass auch versteckte Dateien angezeigt werden sollen).

Rolf

Reinstallation there were problems. Kam always error message (very long, Windows). Can not reproduce I now. 
Otherwise I have to uninstall and re-attempt to install to receive the error message. 
Have therefore the last full backup version replayed. Would you like to send the log file, 
but where can I find this? Have picture of the Explorer also sent. 
The folder: C: \ Program Data \ Acronis \ True Image Home \ I do not find. 
What is the file exactly? What file extension? Where is the folder 
(in Explorer I clicked in view that hidden files to be displayed).

Hello Rolf, lets deal with the logs first - the ProgramData folder is hidden on your system and you must change the Folder and file search options to be able to see it.  I have attached some screen shots showing how it looks on my system and how the settings need to look.

Hallo Steve,

habe den Ordner mit den logDateien gefunden. Habe dann den ganzen Ordner gezipt.  Hoffe, dass ich die logDatei richtig gezipt habe (für mich das erste mal) und du sie öffnen und lesen kannst.

Rolf

Hello Rolf, thank you for the log files, these show me where the problem is here.

In your Service log files, it shows that you are creating a new backup task each time, each task has a new / different task identifier and this is why the task is creating a new full backup when it runs - this is correct behaviour for a new task.

The logs also show that when you run the same task twice, that a full and differential backup are created correctly.

I have attached two documents, one showing your logs with all the different task identifiers, and the second, logs from my own system showing that all the tasks have the same identifier and thus produce differential backups after each full backup.

Working example from your logs:

Hallo Steve,

vielen Dank für die schnelle Fehleranalyse der logDateien. Wenn jetzt also der Fehler bekannt ist, was kann ich machen, damit ich in Zukubft auch defferentielle oder inkrementelle Backups machen kann? Kannst du mir die Lösung geben und eventuell die entsprechenden Einstelungen. Was habe ich bisher falsch gemacht?

Vielen Dank

Rolf

Thanks for the quick error analysis of log files. 
If so now is known of the error, what can I do so that I can also make 
defferentielle or incremental backups in furture? 
Can you give me the solution and possibly the corresponding settings. What I've done wrong?

Hello Rolf, the answer is to keep just one task for each backup operation and reuse that task without making changes.

If you look in your C:\ProgramData\Acronis\TrueImageHome\Scripts folder you should only see a small number of files, one for each of your specific backup tasks.

For example, on my system I have only 3 backup tasks as shown in image Acronis Backup Tasks, these correspond directly to the 3 scripts in the Scripts folder, but show with very different names.  These are the names that are shown in the Service log files.

In order for ATIH to produce incremental or differential backup images, the same script name needs to be used and seen in the Service log files as shown in my earlier post with the Working Logs document.

Your settings are correct but you need to reuse these settings each time, not create them as a new task or make changes.

Hope this helps, Steve

Hallo Steve,

vielen Dank für deine Hilfe und Geduld mit mir. Der "Fehler" ist behoben. Es war mein Unvermögen. Hätte nicht jedesmal ein neues Backup starten müssen, sondern einfach Backup sagen mit den gespeicherten Voreinstellungen. Habe dieses jetzt schon gemacht. Hatte Erfolg.

Letzte Frage:

Wenn ich ein Backup wiederherstellen will (z.B. inkrementell - 1 Vollbackup und 4 inkrementelle Sicherungen, oder 1 Vollbackup und 3 differntielle Sicherungen), wie ist die Reihenfolge der Wiederherstellung? Muss ich erst die inkrementellen bzw differntiellen Sicherungen wiederherstellen und dann das Vollbackup, oder erkennt das Programm die Reihenfolge und macht alles automatisch? Fange ich also mit dem letzten Backup an?

Nochmals vielen Dank für die Hilfe.

Rolf

Hello Steve,
thanks for your help and patience with me. The bug is fixed. 
It was my inability. Had not always have to start a new backup, 
but simply say backup with the stored settings. Have this already done. Had success.

Last question:
If I want to restore a backup (as incremental - 1 full backup and incremental backups 4, 
or 1 full backup and 3 differntielle backups), as is the order of the recovery? 
Do I have to restore the incremental backups or differntiellen and then the full backup, 
or the program recognizes the order and does everything automatically? 
so I'll start with the last backup?

Thanks again for the help.
Rolf

Hello Rolf, that is good that you have got this to work successfully - well done!

When you want to restore your backups, it depends on which type of backup is involved.

For Incremental backups, you will need to decide where you want to start, i.e. with the last incremental backup, or in the case of recovering to a specific point in time, such as before a significant change was made, the incremental that meets that requirement.  Once you select the incremental backup, Acronis will automatically restore all further incremental backups in the version chain and the base full backup.

For Differential backups, each differential contains ALL changes made since the base full backup, so you would just need to decide which Differential backup you want to get back to, then Acronis will again automatically restore that backup and the base full backup to complete the restore process.

The important factor here is to ensure that your backup version chain to be used for recovery is complete, especially for incremental backups.

Please see https://forum.acronis.com/forum/38799#comment-122496 for more information on the differences between the two types of backups.

Regards, Steve
