Backup Scheme

Backup Scheme can help you manage your disk space when you have created too many backup image files created by Aomei Backupper. So if you have enabled "Backup Scheme", Backupper will delete old image files automatically so there is no need for you to delete them manually. For "Backup Scheme", Backupper supports five backup schemes and following paragraphs will describe how they performs.

How to create a Backup Scheme task?

Method 1: If you have not created any backup task, click "Backup", select "File Backup" ( you can select which backup type you are interested in), so it will jump to File Backup interface. At this interface, you can select which folder you want to back up to perform backup process and you can see " Scheme" option.

Method 2: If you have created a backup task, but you have not enabled "Backup Scheme" feature, click "Advanced", select "Edit Backup" so you will see it.

Detailed Introduction to Backup Scheme

Aomei Backupper supports five backup schemes: Differential Backup Scheme, Incremental Backup Scheme, Space Management Scheme, Full Backup Scheme and Other Backup Scheme.

Situation 1:  If you enable the backup scheme when you create the backup task

Situation 1.png

For Differential Backup Scheme

1. Always retain the latest xxx versions of backup image file. When it exceeds the number of versions, the older backup image files will be deleted automatically.
2. Differential backup scheme is similar to a circular queue. When the queue is full and if new members want to join the queue, then old members have to exit from the queue.

Example:

Differential Backup back up what has been added or changed since last full backup and Aomei Backupper provides scheme for you to choose how to deal with the backup image files.

If you tick “Make a full backup before performing backup scheme" option , the procedure is:

FULL(original)→FULL1→DIFF1→DIFF2→FULL2(deleteDIFF1)→DIFF3(deleteDIFF2)→DIFF4 (delete FULL1)

For example, as above, we assume that you have set “3”, and this means AOMEI Backupper will always retain the latest three versions of backup image file. When it exceeds 3 versions, the older backup image files will be deleted one by one. So if here are FULL1.adi, DIFF1.adi, DIFF2.adi and after creating backup FULL2.adi, then the older differential backup DIFF1.adi will be deleted automatically.

If you don't tick “Make a full backup before performing backup scheme" option, the procedure is:
FULL(original)→DIFF1→DIFF2→FULL1(deleteDIFF1)→DIFF3(deleteDIFF2)→DIFF4(delete FULL)

For example, as above, we assume that you have set “3”, and this means AOMEI Backupper will always retain the latest three versions of backup image file. When it exceeds 3 versions, the older backup image files will be deleted automatically. So if here are DIFF1.adi, DIFF2.adi and after creating backup FULL1.adi, then the older differential backup DIFF1.adi will be deleted automatically.

Note: The minimum reserved version is 2, the maximum reserved version is 100.

For Incremental Backup Scheme

Incremental Backup01.png

1. At least retain the latest xxx versions of backup image file. When it reaches to the number of versions, the previous xxx versions of backup image file will be deleted automatically.

2. Incremental backup scheme is similar to a group queue. The former group has to be removed from the queue when the later group meets the requirement of joining the queue. (A group is composed of a full backup and multiple incremental backups)

Example:

Incremental backup scheme allows you to decide newest group of backup image files you are willing to keep and when to delete those you don’t want to keep.

If you tick “Make a full backup before performing backup scheme.” , the procedure is:

FULL (original full backup)→FULL1→INC1→INC2→FULL2→INC3→INC4(delete FULL1, INC1, INC2) →FULL3→INC5→INC6 (delete FULL2, INC3, INC4)

For example, as above, we assume that you have set “3”, and this means you have chosen to keep 3 latest versions of image file. And 3 versions of image files will be regarded as a group. When next group is created, the older group will be deleted automatically. So if here is a group of backup image files as FULL1.adi, INC1.adi, INC2.adi and after creating a new group of backup as FULL2.adi, INC3.adi, INC4.adi, then the older backup group including FULL1.adi, INC1.adi, INC2.adi will be deleted automatically.

If you don’t tick it, the procedure will be:
FULL (original full backup)→INC1→INC2→FULL1→INC3→INC4(delete FULL, INC1, INC2) →FULL2→INC5→INC6 (delete FULL1, INC3, INC4)

For example, as above, we assume that you have set “3”, and this means you have chosen to keep 3 latest versions of image file. And 3 versions of image files will be regarded as a group. When next group is created, the older group will be deleted automatically. So if here is a group of backup image files as INC1.adi, INC2.adi and after creating a new group of backup as FULL1.adi, INC3.adi, INC4.adi, then the older backup group including FULL.adi, INC1.adi, INC2.adi will be deleted automatically.

Note: The minimum reserved version is 2, the maximum reserved version is 100.

For Space Management Scheme

Space Management Backup01.png

1.Please specify for the scheme that create a full backup after xxx versions of differential backups created.

2. This scheme will run as the differential backup way and it is the extension of differential backup. If the program detects insufficient space when performing backup, it will automatically delete old backup image files to free up disk space for storing new backup image files.

Example:

Space Management Scheme helps you manage your backup image files according to your own settings. It can automatically delete older versions of image file when there is not enough space.

If you tick “Make a full backup before performing backup scheme" and we assume that you have set“3 ", then procedure is:

FULL (original full backup)→FULL1→DIFF1→DIFF2→FULL2→DIFF3→DIFF4→FULL3→DIFF5→DIFF6→FULL4(If there is not enough space when doing this backup, Backupper will delete

DIFF1 and if space is still not enough, Backupper will delete DIFF2....)

If you do not tick “Make a full backup before performing backup scheme" option and we assume that you have set“3 ", then procedure is:

FULL1→DIFF1→DIFF2→FULL2→DIFF3→DIFF4→FULL3→DIFF5→DIFF6→FULL4(If there is not enough space when doing this backup, Backupper will deleteDIFF1 and if space is still not enough, Backupper will delete DIFF2....)

For example, as above, we assume you have had several versions of backup image file FULL.adi, FULL1.adi, DIFF1.adi, DIFF2.adi, FULL2.adi, DIFF3.adi, DIFF4.adi. And when you create a new full backup FULL3.adi, the program detects that there is not enough space, then Backupper will delete DIFF1.adi. And if there is still not enough space, Backupper will continue to delete DIFF2.adi. And if space is still not enough, Backupper will delete FULL1.adi.....

For Full Backup Scheme

1. Always retain the latest xxx versions of full backup image file. When it exceeds the number of versions, the older full backup image files will be deleted automatically.

2. Full backup scheme will retain the number of backup image files you specified. When it reaches to the specified number, the program will automatically delete old backup image files.

Example:

Full backup scheme provides you the function of manage the existing backups, which is to let you make decisions on which to retain and which to delete.

If you tick “Make a full backup before performing backup scheme.” , the procedure is:

FULL (original full backup)→FULL1→FULL2→FULL3→FULL4 (delete FULL1)→FULL5 (delete FULL2)→FULL6 (delete FULL3)→FULL7 (delete FULL4)

For example, as above, we assume that you have set “3”, and this means you want to always retain the latest 3 versions of full backup image file. When it exceeds 3 versions, the older version of backup image file will be deleted automatically. So if here are FULL1.adi, FULL2.adi, FULL3.adi, and after creating a new full backup FULL4.adi, the older backup FULL1.adi will be deleted automatically.

If you don’t tick it, the procedure will be:
FULL (original full backup)→FULL1→FULL2→FULL3(delete FULL)→FULL4 (delete FULL1)→FULL5(delete FULL2)→FULL6 (delete FULL3)

For example, as above, we assume that you have set “3”, and this means you want to always retain the latest 3 versions of full backup image file. When it exceeds 3 versions, the older version of backup image file will be deleted automatically. So if here are FULL1.adi, FULL2.adi, and after creating a new full backup FULL3.adi, the older backup FULL.adi will be deleted automatically.

Note: The minimum reserved version is 1, the maximum reserved version is 10.


Situation 2:  If you have done several INC(DIF or Full) backups but you have not enabled Backup Scheme and you want to enable it now

For Differential Backup Scheme

Differential Backup0001.png

Example:

If you tick “Make a full backup before performing backup scheme.” , the procedure is:

FULL(original)→DIFF1(original)→FULL1→FULL2→DIFF2→DIFF3→FULL3(deleteDIFF2)→DIFF4(deleteDIFF3)→DIFF5(delete FULL2)

For example, as above, we assume that you have set “3”, and this means AOMEI Backupper will always retain the latest three versions of backup image file. When it exceeds 3 versions, the older backup image files will be deleted automatically. So if here are FULL1.adi, FULL2.adi, DIFF2.adi, DIFF3.adi and after creating backup FULL3.adi, then the older differential backup DIFF2.adi will be deleted automatically. FULL and DIFF1 produced before you enable the "backup scheme" will not be deleted.

If you don’t tick it, the procedure will be:
FULL(original)→DIFF1(original)→FULL1→DIFF2→DIFF3→FULL2(deleteDIFF2)→DIFF4(deleteDIFF3)→DIFF5(delete FULL1)

For example, as above, we assume that you have set “3”, and this means AOMEI Backupper will always retain the latest three versions of backup image file. When it exceeds 3 versions, the older backup image files will be deleted automatically. So if here are DIFF1.adi, DIFF2.adi and after creating backup FULL1.adi, then the older differential backup DIFF1.adi will be deleted automatically. FULL and DIFF1 produced before you enable the "backup scheme" will not be deleted.

For Incremental Backup Scheme

Incremental Backup0002.png

Example:

Incremental backup scheme allows you to decide newest group of backup image files you are willing to retain  and when to delete those you don't want to retain.

If you tick “Make a full backup before performing backup scheme.” , the procedure is:

FULL(original)→INC1(original)→INC2(original)→FULL1→FULL2→INC3→INC4→FULL3→INC5→INC6(delete FULL2, INC3, INC4)→FULL4→INC7→INC8 (delete FULL3, INC5, INC6)

For example, as above, we assume that you have set “3”, and this means you have chosen to keep 3 latest versions of image file. And 3 versions of image files will be regarded as a group. When next group is created, the older group will be deleted automatically. So if here is a group of backup image files as FULL1.adi, FULL2.adi, INC3.adi, INC4.adi, after creating a new group of backup as FULL3.adi, INC5.adi, INC6.adi, then the older backup group including FULL2.adi, INC3.adi, INC4.adi will be deleted automatically. FULL, INC1, INC2 created before you enable the "backup scheme"  will not be deleted.

If you don’t tick it, the procedure will be:
FULL(original)→INC1(original)→INC2(original)→FULL1→INC3→INC4→FULL2→INC5→INC6(delete FULL1, INC3, INC4)→FULL3→INC7→INC8 (delete FULL2, INC5, INC6)

For example, as above, we assume that you have set “3”, and this means you have chosen to keep 3 latest versions of image file. And 3 versions of image files will be regarded as a group. When next group is created, the older group will be deleted automatically. So if here is a group of backup image files as FULL1.adi, INC3.adi, INC4.adi and after creating a new group of backup as FULL2.adi, INC5.adi, INC6.adi, then the older backup group including FULL1.adi, INC3.adi, INC4.adi will be deleted automatically. FULL, INC1, INC2 produced before you enable the backup scheme will not be deleted.

For Full Backup Scheme

Full Backup00003.png

Example:

Full backup scheme provides you the function of manage the existing backups, which let you make decisions on which to retain and which to delete.

If you tick “Make a full backup before performing backup scheme.” , the procedure is:

FULL(original)→FULL1(original)→FULL2(original)→FULL3→FULL4→FULL5→FULL6 →FULL7 (delete FULL4)

For example, as above, we assume that you have set “3”, and this means you want to always retain the latest 3 versions of full backup image file. When it exceeds 3 versions, the older version of backup image file will be deleted automatically. So if here are FULL3.adi, FULL4.adi, FULL5.adi, and after creating a new full backup FULL7.adi, the older backup FULL4.adi will be deleted automatically. FULL, FULL1, FULL2 produced before you enable the backup scheme will not be deleted.

If you don’t tick it, the procedure will be:
FULL(original)→FULL1(original)→FULL2(original)→FULL3→FULL4→FULL5→FULL6(delete FULL3)→FULL7 (delete FULL4)

For example, as above, we assume that you have set “3”, and this means you want to always retain the latest 3 versions of full backup image file. When it exceeds 3 versions, the older version of backup image file will be deleted automatically. So if here are FULL3.adi, FULL4.adi, FULL5.adi, and after creating a new full backup FULL6.adi, the older backup FULL3.adi will be deleted automatically. FULL, FULL1, FULL2 created before you enable the "backup scheme" will not be deleted.

For Other Backup Scheme

Other Backup Scheme.png

After the next backup finishes and create a new image file, the program will automatically delete all the previous image files of the backup task when they remain more than XXX Days/Weeks/Months.

FULL(original full backup)→FULL1→INC1→INC2→FULL2 (delete FULL1, INC1 and INC2) →INC3→INC4→FULL3 (delete FULL2, INC3 and INC4)

There are two ways to delete all the previous versions of backup image file:

By version: For example, we assume you have these versions of backup file as above and you have selected “3 versions” , then after creating FULL2.adi automatically, then FULL1.adi, INC1.adi and INC2.adi will be deleted.

By time: For example, we assume you have several backups as above and you have selected “3 days”. If FULL1.adi, INC1.adi and INC2.adi are created three days ago, after creating FULL2.adi automatically, these previous versions (FULL1.adi, INC1.adi and INC2.adi) will be deleted.

Notes:

  • For "Backup Scheme" feature, this function is in paid version. So if you want to experience it, then you need to upgrade free version to paid version.

  • If you have created several backup  image files before enabling "Backup Scheme", then these image files would not be deleted after enabling "Backup Scheme".

  • If you create a scheduled backup task and you want to enable "Backup Scheme", then Backupper will run it as backup scheme method you select to perform. For a general scheduled backup task, Backupper will perform it as incremental backup by default.
