Copying encrypted files
Previous
If Secure Copy cannot encrypt the copied file, you can choose to create an unencrypted file on the target. When copying a file that is encrypted on the source, Secure Copy attempts to encrypt the file on the target using the Encrypting File System (EFS). If Secure Copy is unable to encrypt the file on the target, the copy will fail unless this option is selected.
To copy encrypted files
1 Click Jobs, and expand the job
2 Click Other File Options.
3 Select Allow copy of encrypted files as unencrypted if encryption fails.
Copying off-line/stub files
Previous
By default, offline/stub files are skipped in a copy job. You can choose to copy files that are on an offline storage device, resulting in the original file being recalled from offline storage.
To copy offline/stub files
1 Click Jobs, and expand the job.
2 Click Other File Options.
3 Select Copy off-line files/stub files.
Copying recently modified files
Previous
By default, files where the last-modified date and time differs by less than 2 seconds are skipped in a copy job.
File-time granularity is 100 nanoseconds on NTFS and 2 seconds on FAT, so copying a file from NTFS to FAT causes file times to be rounded to a value that the FAT file system can manage. When both the source and destination volumes are NTFS, the file times are compared exactly. When either the source or destination volume is not an NTFS volume, Secure Copy considers file times to be identical if they are within 2 seconds of each other. Without this 2-second margin, Secure Copy might classify unmodified files as older or newer files, which would result in unnecessary copying of unchanged files.
Sometimes you may want to override this handling of file times. For example, you copy an NTFS tree to a FAT volume. Secure Copy rounds the file times. You then copy the FAT tree (with its rounded file times) to a local NTFS drive. Later, when you want to recreate the original tree exactly, you do not want to refresh the entire tree.
To copy recently modified files
1 Click Jobs, and expand the job.
2 Click Other File Options.
3 Select Ignore NTFS/FAT time differences up to 2 seconds.
Using compression
Previous
|
|
NOTE: Compression is not performed by Secure Copy; it is performed by the operating system. The compression function is performed at the same time as the write function, which could extend the write time of the file and thus extend the duration of data migration. |
To use compression
1 Click Jobs, and expand the job.
2 Click Other File Options.
3 Select how to handle compression.

Option |
Description |
|
Never compress target files |
Disregards any file or folder compression that may exist on the source or target. Copies all files and folders uncompressed. This option offers the greatest speed for the copy process, and is recommended if there is not a space requirement on the target. |
|
Always compress target files |
Select only in cases when space is a premium as it adds substantial overhead and time to the copy job. This option also adds to the fragmentation on the target volume. Use only if absolutely necessary. |
|
Compress target files only if source is compressed |
Select to compress the files and folders on the target if they are compressed on the source. This option provides consistency among the file systems on the source and target, but also adds to the time required to perform the process. Use only if necessary. |
