access to backed up data

Thread needs solution

can you delete/modify the backed up data?

Mainly looking to delete un-needed backed up files to make room on the drive.

Hello Brad,

Yes, you can delete un-needed backup image files but the recommended method of doing so is via the auto-cleanup options for the backup task that created the files rather than just deleting them using Windows / File Explorer.  The reason for doing it via auto-cleanup is that this also manages the information in the Acronis database for the backup image files and prevents getting error messages later about missing backup files.

If you do delete backup files via Explorer, then you should perform a Validation of your backup task after doing so and take the option to Ignore any missing (deleted) backup files.

See the ATIH 2016 User Guide pages for Deleting backups and backup versions for more information and Automatic cleanup rules which states:

To delete obsolete backup versions automatically, you can set one of the following cleanup rules:

  • Delete versions older than [defined period] (available for full method only) - Select this option to limit the age of backup versions. All versions that are older than the specified period will be automatically deleted.
  • Delete version chains older than [defined period] (available for incremental and differential methods only) - Select this option to limit the age of backup version chains. The oldest version chain will be deleted only when the most recent backup version of this chain is older than the specified period.
  • Store no more than [n] recent versions (available for full method only) - Select this option to limit the maximum number of backup versions. When the number of versions exceeds the specified value, the oldest backup version will be automatically deleted.
  • Store no more than [n] recent version chains (available for incremental and differential methods only) - Select this option to limit the maximum number of backup version chains. When the number of version chains exceeds the specified value, the oldest backup version chain will be automatically deleted.
  • Keep size of the backup no more than [defined size] - Select this option to limit maximum size of the backup. After creating a new backup version, the program checks whether the total backup size exceeds the specified value. If it's true, the oldest backup version will be deleted.

Also can you set a rule or something that will backup files with certain dates? Like if I wanted to backup files with dates from 5-23-2016 thru present?

Yes to 2014.  http://www.acronis.com/en-us/support/documentation/ATIH2014/#16515.html  and  http://www.acronis.com/en-us/support/documentation/ATIH2014/#13712.html

No to backups filtered by date.  Acronis does not have an option to only backup files of a certain date.  It will backup everything in the disk(s), partion(s) or folder(s) you tell it to at that point in time (excluding those items in the exclustions tab - exclusions only work by extension or file path).   Basically, it will backup everything in the lcoations you tell it to with a full backup the first time. You can then configure incrementals or differentials to only backup changes unil the next full runs.  How long you space out incrementals and differentials is entirely up to you, but a good backup should not extend those out too long.  

Example of an incremental backup... 1 full + 6 incremnetals (1 per day / daily) = 1 week and 1 version chain.  Keep 4 version chains = 1 month.  After the 5th full backup, then version chain 1 is automatically deleted and the process repeats so that you always have about 4 weeks of backups. 

Of course ou can have more incrementals and as many as you want before the next full.  You can also keep more version chains as well. But, since each subsequent incremental depends on all the ones before it, the longer it goes, the more prone to corruption the backup chain can become overtime due to issues in Windows, disks failing, etc so it is really the # of incremetnals or differentials you choose to have before running another full that should be considered.
