Profile Properties – File Options
!This profile property isn't available unless Expert Mode is activated.
Copy Method
This option enables you to specify the internal copy method used by AllSync for copying files.
Default setting: Method B.
Yes = fastest copy method
When the return value of the external program is not equal to zero, an error message is outputted to the log file.
| Copy Method Properties | A | B | C | D |
|---|---|---|---|---|
| Progress indicator while copying a file | - | Yes | Yes | - |
| Resume interrupted copy operation of a file | - | Yes | Yes | - |
| Aborting of a copy operation | - | Yes | Yes | - |
| Copying of file attributes | Yes | Yes | Yes | ? |
| Copying of the modified date | Yes | Yes | Yes | ? |
| Copying of the created date | - | - | Yes | ? |
| Copying of the accessed date | - | - | Yes | ? |
Which copy method should you use?
Following from the results produced by various copying tests we can give the following recommendations:| Copying Scenario | A | B | C |
|---|---|---|---|
| From computer A to computer B via a network link | Yes | - | Yes |
| From hard drive A to hard drive B on a computer | Yes | Yes | - |
| Hard disk to USB stick | Yes | Yes | - |
| From a USB hard drive to a USB hard drive | - | - | Yes |
Yes = fastest copy method
Copy Method C
Upon starting the copy operation, the destination file is created with a modified date which is older than that of the source file. This prevents AllSync from recopying the source file in the event the link to the destination folder is interrupted.Data packet
This setting enables you to specify in bytes the size of the data packets used to read from the source file into main memory and then to the destination file.Pause
This setting enables you to specify the length of the pause in milliseconds between copying data packets.Copy Method D
This option enables you to specify an external program like Microsoft's Xcopy for the copy operation of the source file to the destination folder. The following variables (%) are available to you for passing the source and destination file:- %1 = source file (example: C:\Data\Info.doc)
- %2 = destination file (example: D:\Backup\Data\Info.doc)
- %3 = destination folder (example: D:\Backup\Data)
When the return value of the external program is not equal to zero, an error message is outputted to the log file.
Automatic selection of the fastest copy method
With this option the fastest copy method will be automatically determined for every source and destination folder pair. The copy method C with a data packet of 300.00 bytes will be used if the source or destination folder is determined as a network folder or the folder path start with the characters "\\". Otherwise the copy method B will be used.Copy Attempts
This option enables you to specify that a file is to be recopied in the event there is an error while copying it.
You can specify the number of copy attempts for a file and the interval between them in seconds.
The default value of 1 for the number of copy attempts causes a file to be copied only once and no renewed attempts to be made when an error occurs.
Resume interrupted copy operation of a file
This option enables a copy operation of a file to be resumed at the point it was interrupted when another copy attempt is made.Advanced Rules
You can additionally specify advanced rules for certain errors and enter them in the text pane. One rule is entered per line. Each rule must contain the following items, separated by a comma:- Error no.
- Number of copy attempts (1-99)
- Interval in seconds between copy attempts (1-99)
- Here you specify which action is to be performed when a copy attempt is unsuccessful. The following values are possible:
0 = Don't abort profile and continue with the next file
1 = Abort profile
2 = Abort processing of the current source and destination folder and continue with the next folder pair
Examples:
- Rule "112,1,1,1" causes no further copy attempt to be made and the profile to be aborted when error 112 occurs.
- Rule "64,6,15,2" causes an additional five copy attempts to be performed in intervals of 15 seconds when error 64 occurs. If the file cannot be copied without any errors, processing of the current source and destination folder is aborted and processing is continued with the next folder pair.
- Rule "32,3,10,0" causes two additional copy attempts to be made in intervals of 10 seconds. If the file cannot be copied without any errors, processing is continued with the next file.
Modifying File Attributes
These options enable you to modify the attributes of the source or destination file after copying.
The attributes aren't modified unless copying was successful.
The following attributes can be set and deleted:
- Write-protected
- Hidden
- Archive
Verification Check (of the contents of copied files)
Activating this option causes the contents of the source and destination file to be compared after being copied.
An error is logged if the contents of the two files isn't identical.
The following comparison methods are possible:
You can also specify whether no comparison is to be performed of files above a certain size.
- Byte for byte
- CRC32 (32-bit)
- MD5 (128-bit)
- SHA (160-bit)
Data packet
This setting enables you to specify in bytes the size of the data packets used to read from a file into main memory.Pause
This setting enables you to specify the length of the pause in milliseconds between reading the individual data packets.You can also specify whether no comparison is to be performed of files above a certain size.
Options
Transfer attributes of source files to existing destination files
This option enables you to transfer the attributes of a source file to an existing destination file during a copy operation.
The attributes aren't transferred unless the source and destination files are identical on the basis of the copy rules.
Transfer upper- and lowercasing of the source files to existing destination files
This option enables you to transfer the modified upper- and lowercasing of a source file to an existing destination file during a copy operation.
The modification is not made unless the source and destination files are identical on the basis of the copy rules.
