The differential backup mode is similar to the “complete + incremental” backup mode described above, except that each differential backup (i.e. If you choose to keep only one incremental copy, this can be also considered a differential backup. This allows to keep a complete history of file changes, and to save space on disk.

#IPERIUS BACKUP REVIEWS FULL#

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.

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. In the destination folder you will have a folder structure like that shown in the picture below: 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. 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. The full backup mode is generally not recommended, because it’s slower and requires more disk writing operations and network bandwidth. 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. With this mode, Iperius always copies all files, overwriting those existing in the destination. The full backup doesn’t make any check on file existence or file date. You can also specify the number of copies to keep, to have the same full/incremental backup replicated more times, and overwritten in rotation. 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. The first backup will copy all files, while the next ones only new or changed files (overwriting old files in the destination). Let’s see them below:īy default, in the local, network or FTP destinations, Iperius will use the incremental mode.

In all the file-by-file backup procedures (such as NAS backup or FTP backup) you can specify different backup types.

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. 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. The first time Iperius copies all files, while the next times, it only copies new or changed files. The incremental backup allows to optimize backup duration and performance. It allows to make many backup types, using various backup modes: full, incremental and differential.
