Default Problem copying large file to external USB

I have an occasional problem and hope someone can offer a suggestion.

My system is a Win 7 with an ssd C drive. For backup I use Acronis,
and have used it for years starting with Win XP.

It is set to do a full backup once a week and an incremental on other
days. The backups are written to my internal E drive, and I copy those
to an external USB drive for extra protection to avoid loss in case my
entire desktop were to die.

My ssd is at less than 50 per cent used as are the internal E drive
and the external USB.

I never have a problem when copying an incremental file, typically
about 3 gigs, from E to the external usb but about every other time
when I copy the full backup Acronis TIB file, usually 45 to 50 gigs,
the progress bar will hang while showing 3 or 5 or some similar number
of minutes remaining. The only way I can clear the message is a manual
power off. Trying to cancel the operation or using the task manager to
stop the process does not work.

After I reboot and check the usb drive it shows that the file was
copied, it has the same file size as the one on the internal E drive
and a CRC check indicates no error.

Any suggestions as to why this happens and how to avoid it?

Have you checked the external drive for errors?

My 100GB SSD has two partitions, C and J. C contains applications that
insist on being installed on a C-drive, including Windows 7. J contains
most other applications. For some reason, Office is on my D-drive,
which is a "spinner"; this was supposed to be only for data. (I did not
configure this; it was done by the person who setup my PC.)

My C partition occupies less than 50GB, but it could grow to 64GB. My J
partition is smaller than the C partition. I backup the C and J
partitions either fully or incrementally.

My D-drive is 900GB, of which I am only using less than 200GB. I backup
my D-drive by files, excluding photos. I backup the photos separately,
again by files. Again, I either backup these fully or incrementally.

All backups go to my D-drive and then to a removable hard drive. Before
moving the backup files to that removable drive, I encrypt them using
PGP. The removable drive is stored away from my PC. I keep the backups
on my D-drive in case I need to restore a file that I clobbered.

Since I use Acronis with compression, none of my backups reach the sizes
of their sources. I backup weekly in the following cycle:
week 1: full C, incremental J, incremental D
week 2: incremental C, full J, incremental D
week 3: incremental C, incremental J, full D
weeks 4-6: repeat weeks 1-3
Just before doing a full backup, I erase the oldest backup and its
increments. Thus, I have as many as six weeks of backups. For each
partition or drive, I have a full, two increments, and another full.
Depending on where I am in the cycle, that latter (and later) full
backup has no, one, or two increments.

I backup my photos only when there are a number of new photos since my
last backup. Instead of a full plus two incrementals, photos have a
full and three incrementals. I follow a similar scheme with backing-up
the installer files of new and updated applications; I keep those
installer files on a flash drive and backup directly from the flash
drive to the removable drive. Neither photos nor installer files are
encrypted for the removable drive.

All this helps to reduce the size of each backup and also reduce the
time spent doing backups. Because much of the backed-up data are
binaries, PGP's encryption -- which includes compression -- does little
to reduce the sizes of my backups. My largest encrypted backups are
less than 18GB, which I have no problem moving.

Yes I have checked the external drive for errors. None reported. I
also use compression for my Acronis files.

It's a silly suggestion, but someone has to ask, does the external
USB get powered down by Windows after some minutes of inactivity? This
could cause the backup software to sit on a verify or something
waiting for the drive to respond.
That would explain why it only happens with the larger filesets.
Mand.


Normally the external USB is powered off. I turn it on a few minutes
before I expect to use it and then use the remove device function
followed by a power down. In other words it is only on for five to ten
minutes each day.

Default Problem copying large file to external USB

In article , havant1
@earthlink.net says...
software


I've occassionally had the same problem but instead it was while copying
very large folders of mp3 files, e.g. 700+Gb. I ended up using a 3rd
party tool to do it rather than the frustration of it sometime stalling
along the way leaving some files copied and others not. Freefilesync is
what I use. I only use it to basically sync a couple of folders.

I'm unsure if some timeout isn't involved given of the six
external/portables I have the only two have never had any issue of any
sort are the two externals which both have full size 3.5" internal
drives in them (basically they're enclosures) rather than 2.5" laptop
drives. One's a SATA 1Tb WD other is a IDE 500Gb WD.

On solution is to use a file splitter such as Max Split from
http://www.softpedia.com/get/System/File-Management/Max-Split.shtml.

I am not sure this particular splitter installs or works with Windows 7.
I last used a version with Windows 98 when I was saving backups on Zip
drives. Each full backup was too large for on Zip drive, so I had to
split it. I now have a removable hard drive that has much more capacity
than any Zip drive.

Acronis is a company name, not a product name.

Is the USB drive using FAT32 for its formatting? If so, 2 TB is the
largest partition size on that drive. You need to reformat the USB
drive to use NTFS, or ...

Configure Acronis True Image (if that's what you are using) to slice its
backup files. If you use a 3rd party file slicing utility, you'll have
to use it again to re-merge those files so Acronis True Image can read
those files. Having ATI do the file slicing so each backup file is
complete in the format that ATI uses to read them. Or ...

Get a different USB-attached HDD. Some will go idle (spin down) even
when they should be busy. Because of the next described problem, the
USB drive may think it is not busy so it sleep. Some "green" drives can
be a bitch to awaken. Stay away from green-qualified drives: too short
an idle time for when they sleep, the low-power mode is programmed in
the drive's firmware so nothing you do in Windows power optios will keep
that USB drive constantly awake. Or ...

Make sure you are using the detailed or list view in Windows Explorer
during the copy. You don't want it hanging on a huge file trying to
refresh the thumbnail cache. Thumbnails on huge files can take a long
time to dig into to find an image to present as a thumbnail, and there
probably is no graphic image in the backup file to find, anyway.
Explorer ends up using the generic thumbnail for the data type, if
assigned to a handler, but it will waste time looking for an image to
use for the thumbnail. You might a slowly left-to-right moving green
progress bar travelling through the address bar. That's Explorer
rebuilding the thumbnails which you don't need on a non-graphics file.

Is there a hang or long pause when you copy the backup file (full) from
your E: drive (is that an HDD?) to a temp folder on C: (SSD) if there is
room on C:?
