JetBackup treats each account as an entity.
The procedure applied to each account is:
The information gathered according to the backup job configuration.
In incremental backup job the steps that actually consume disk space are:
All other steps are done by transferring the data directly to the destination.
In compressed/archived backup job all information gathered by the different steps appended to an archive file. If the job type is compressed then we'll compress the archive file, making it ready for transfer.
Please Note in this mode the minimal required space is 110% of the largest account.
At this stage, we transfer the compressed/archived backup to the destination.
Remove the compressed/archived backup file on local.
