4.2.6.6 Initial seeding
This backup scheme is available when Acronis Cloud Storage is selected as the backup destination. A
backup is only successful if you have an Initial Seeding license.
The Initial Seeding service might be unavailable in your region. To find more information, click here:
http://kb.acronis.com/content/15118.
Initial seeding enables you to transfer the first backup, which is full and usually the largest, to the
cloud storage on a hard drive instead of over the Internet. Subsequent backups, which are all
incremental and thus usually much smaller, can be transferred over the Internet after the full backup
has arrived in the cloud storage.
If you back up 500 GB of data or more, initial seeding ensures faster delivery of the backed-up data
and lower traffic costs.
Please refer to the "Initial Seeding FAQ (p. 214)" section for more details.
4.2.7 Archive validation
Set up the validation task to check if the backed-up data is recoverable. If the backup could not pass
the validation successfully, the validation task fails and the backup plan gets the Error status.
Validation of a file backup imitates recovery of all files from the backup to a dummy destination.
Validation of a volume backup calculates a checksum for every data block saved in the backup.
To set up validation, specify the following parameters
1. When to validate – select when to perform the validation. As the validation is a
resource-intensive operation, it makes sense to schedule the validation to the managed
machine's off-peak period. On the other hand, if the validation is a major part of your data
protection strategy and you prefer to be immediately informed whether the backed-up data is
not corrupted and can be successfully recovered, think of starting the validation right after
backup creation.
2. What to validate – select either to validate the entire archive or the latest backup in the archive.
Validation of the archive will validate all the archive’s backups and may take a long time and a lot
of system resources.
Validation of the latest backup may also take time, even if this backup is incremental or
differential, and small in size. This is because the operation validates not only the data physically
contained in the backup, but all of the data recoverable by selecting the backup. This requires
access to previously created backups.
3. Validation schedule (appears only if you have selected On schedule in step 1) - set the schedule
of validation. For more information see the Scheduling (p. 58) section.
4.2.8 Backup plan's credentials
Provide the credentials for the account under which the plan will run. By default, the plan runs under
the agent service account, if created by a user having administrative privileges on the machine. If
created by a regular user, such as a member of the Users group, the plan runs under this user's
account.
To specify credentials explicitly
1. If you have administrative privileges on the machine, select Use the following credentials.
Otherwise skip this step.
