I got some good advice from you guys on the pros and cons of splitting large
files (MS-SQL database dumps) for backups and in return here's my findings:
1) Backing up one large file or lots of .part files takes about the
same amount of time, as expected, due to rsync only copying changes
2) Many of the .part files are identical on a day-by-day basis so we
have significantly reduced the amount of disk space the backups take up due
to BackupPC's use of hard-linking
The tool we use to split, verify and join the .part files is called Swiss
File Knife (sfk), It's Open Source & available for Windows and Linux. Sfk
has a lot of other useful features too and is well worth a look if you've
not seen it before:
