Iperius is a complete and flexible backup software for Windows. It allows to make many backup types, using various backup modes: full, incremental and differential.

The incremental backup allows to optimize backup duration and performance. The first time Iperius copies all files, while the next times, it only copies new or changed files.

With Iperius you can create backup strategies to keep a complete history of file changes, creating each day a new backup and so a new version of files. In the Drive Image Backup, for example, it is performed a progressive update of the disk image file, thanks to the block-level mode, that copies in the backup file only the disk blocks that have been modified.

In all the file-by-file backup procedures (such as NAS backup or FTP backup) you can specify different backup types. Let’s see them below:

1. Incremental backup (default):

By default, in the local, network or FTP destinations, Iperius will use the incremental mode. The first backup will copy all files, while the next ones only new or changed files (overwriting old files in the destination). The final result of this backup type is always a full copy, that is updated at each new backup. This mode is the recommended one, because it increases performance, reducing disk writing operations and network bandwidth usage for remote backups.

You can also specify the number of copies to keep, to have the same full/incremental backup replicated more times, and overwritten in rotation.

2. Full backup:

The full backup doesn’t make any check on file existence or file date. With this mode, Iperius always copies all files, overwriting those existing in the destination. The time needed to complete the backup will be always the same, because all files are copied again every time. If you specify more then 1 copy, you will have multiple full backups. The full backup mode is generally not recommended, because it’s slower and requires more disk writing operations and network bandwidth.

3. Full backup + incremental copies:

This mode could be considered the more complex one, because it allows to create a granular backup strategy and to keep a complete history of file changes. Using this mode, Iperius will first create a full copy, then, in the next backups, it will create numbered folders only containing new or modified files since the last full or incremental backup.

In the destination folder you will have a folder structure like that shown in the picture below:

backup-full-incremental

The folder with the “-FULL” suffix will always contain the full copy, while the numbered folders will contain only new or changed files since the previous backup. For example, in a weekly scheduled backup, the first full backup could be made on Monday, while the incremental ones on the next days. If a file is modified every day, you will have a copy of it in each numbered folder. This allows to keep a complete history of file changes, and to save space on disk. If you choose to keep only one incremental copy, this can be also considered a differential backup.

Complete backup + differential copies:

backup-differenziale
The differential backup mode is similar to the “complete + incremental” backup mode described above, except that each differential backup (i.e. in the numbered folders) will always include all files which are new or which have been modified since the COMPLETE backup was done (and not since the previous backup was done, as is the case with the incremental backup). This means that the differential backup will generally become larger than the incremental one as more time passes since the last occasion on which a COMPLETE backup was made.

Even in this case, the destination folder will have the structure shown in the following figure:

backup-full-incremental

The folder with the “-COMPLETE” suffix will always contain the complete copy, with all the files inside, while the numbered folders will contain only those files that are new or that have been modified since the COMPLETE backup. As part of a weekly schedule, the COMPLETE backup could be run on the first day, while the other backups would be done in the days that follow. The differential copies will always contain all the files that have been changed or added since the last COMPLETE backup was carried out.

These backup types are available for all backups to local or external hard drives, to network folders or to FTP servers. For all these backups it can be also used the synchronization, to automatically remove old files from the destinations if they don’t exist anymore in the source folders.

    I’dd like to copy files from my server to a second a NAS, an overwrite older versions of thes files. How can i do this. The options i can find are all backup sets…

    1. Iperius Backup Team Article Author

      Hi, by default Iperius simply copies all files to the destination, creating first a full backup and then updating it with new or modified files. You don’t need to change any setting, simply use the default ones.

    We’re pretty interested in Iperius, but this article is out of date and doesn’t explain any steps for the updated azure portal

    1. Iperius Backup Team Article Author

      Hello,

      thank you for submitting this problem. We will investigate to see if Microsoft changed the Azure console recently.

      Anyway, basically you need only to get credentials to write into your space.

    Hello Team

    My Question is I have set Full Backup + Incremental Copies as 31 days
    No what will happen after 31 days

    Will it again take full backup and incremental for 31 days

    or

    the backup job will stop

    Hi,

    How would I configure this to take a full backup every Saturday and incremental backups every other day of the week?

    Thanks.

    Hello Team,

    Need advice. I’m a new with Iperius and I need make the ESXI backup for different machines with a different schedule. When I add server and select proper vm I need fill destination folder but also I have a tab “Destination” with amount backup option which specify how many copies I should keep.
    Question is: where should I indicate destination in the main wizard? But if I selected only in main window how can I select amount of copies?

    1. Iperius Backup Team Article Author

      Hi,

      the additional destinations in the “Destinations” panel are optional. You can add an additional destination on a subolder to keep more copies of the virtual machine backups.

    Hello;
    Is it possible to make a incremental backup to cloud services, like google drive, OneDrive, etc?
    Thank you.

    Hi,

    I need to do a backup on following method. Initially to take a full backup and after that keep only incremental backups everyday on each month. I don’t need to update the full backup afterwards. Can you please help me on this with how to configure.

    1. Iperius Backup Team Article Author

      Hi,

      you can configure a backup that is copied on a folder named with the month name, using the related special variable in the custom destination folder name. Then, you can configure the backup type “Create a full backup and a number of incremental copies” and set the number of copies to 31.

    I have installed iperiusbackup free version on server 2012 R2. I have scheduled backup 2 times a day, and repeat is set for 31 days. What frustrates me is that you backup system takes full backup and not incremental backup every time. I even tried Hash MD5 without success. I will uninstall the software and buy another product if this issue continues. Please help me with this issue.

    1. Tor Bruheim

      My mistake. I forgot to set it to incremental. Sorry. This was really stupid of me :) It is working nicely.

    Hi,

    How do I setup a backup set to run this way:

    1. Saturday – Full backup
    2. Monday to Friday – Incremental
    3. Keep Full + Incremental backup sets for 4 weeks. Overwrite the first Full Backup set on fifth Saturday or just delete the first Full + Incremental set.

    Thank you.

    hello i want to incremental backup but daily folder wise like
    Full Backup
    Incremental date 23/11/2016
    Incremental date 24/11/2016

    like this i dont want replace my file how to do that

    1. Iperius Backup Team Article Author

      You cannot add the date to the folder name.
      However, you can make this using numbered folder.
      You simply have to specify a destination, then the backup type “full+incremental” and the number of copies to keep

  11. Robert Sykes

    Hi I am wanting to use FTP offsite which I have setup with full backup and incremental as default.

    Is it possible to do the initial full backup to an external HDD and the copy to the FTP server as this will be quicker than transferring 100gb of data over the internet. Then the incremental backups can run after that?

    Thanks
