tar ~/Documents to create a backup and my
.tgz file turns out to be about 683 MB. I allow my Ubuntu One upload speed to be about 2.5 Mb/s. The sync takes several hours. My Power Management setting is "never suspend". I might on some occasions reboot Ubuntu in the middle of the sync in order to switch to Windows to print a file since Ubuntu does not have a driver for my printer. I get no complaints so this seems like a permissible operation. After the sync completed I downloaded the file from the Ubuntu One website. Strangely the file is now 619 MB and using the
diff utility I can see a message that says the binary files are not identical.
Double-clicking the downloaded
.tgz file opens the Archive Manager and I get this:
gzip: stdin: unexpected end of file tar: Unexpected EOF in archive tar: Error is not recoverable: exiting now
How did this file get corrupted?
