Acebackup compression

Post by J.Little » January 3rd, 2013, 10:15 am

Hi,

Does anyone know what compression is used by acebackup?
Due to the software not being able to successfully backup/restore files over 4GB
i'm stuck having to try and recover outlook PST files that are broken and fail
to restore, so i need the files uncompressed so i can use other software to
attempt repairs.

Thanks

This depends on the type of compression you select. In AceBackup 3, you can choose from three types of compression: Fastest, Default and Best.

You can change the type of compression via “Project” -> “Properties”.

The problem of very large files has actually been solved since AceBackup 2004. Back then, we introduced a special method for processing very large files, which significantly increased such files’ processing speed.

Yet when processing large files, please make sure that your disk containing the temp directory has enough free space (approx 500 Mb) for auxiliary files. The reason is that AceBackup creates an auxiliary file in the temp directory during backup/restore. Once the operation is completed, this file is deleted.

(Pleas also see viewtopic.php?f=14&t=902.)

Also, please note that AceBackup cannot backup files that are being used by another program. E.g. you cannot backup an Outlook.pst file while MS Outlook is running. In this case, simply add the file to a WinZip archive while MS Outlook is running.

Hi,

Integrated zip compression is used by acebackup. Yeah, your file must be damaged as the backup process was not completed successfully. In this case, you need to repair your pst file and you can do this using "scanpst.exe" which is an inbuilt tool of Outlook. There is a step by step process to operate this solution, to know all the steps, read this post: Repair damaged PST File.
