I have a client with the following backup requirements.
What the client has:
- Client has 30 PCs on LAN and 10 Laptops on the field with rudimentary internet access via 3G USB Sticks, all running various flavours of windows.
- main site has active directory on Windows 2003 servers and a dedicated 512kbps internet connection.
- files to be backed up include MS Office docs, spreadsheets, presentations, PDFs, CAD drawings, and Outlook PST files (they use POP3).
- size vary from a few KB to15 GB for PST files.
What the clients wants:
- All files in the main office to be backed up incrementally on a daily basis from each workstation to a NAS device on the LAN.
- PST files and other large files should be delta-backed up, to save time and bandwidth (LAN).
- Further, smaller files ( MS Office, PDFs, Accounting, CAD etc) have to be backed up daily to a different NAS device located at a remote office, either separately or replicated from first NAS device.
- Also, the client wants larger file (PSTs, Videos, Audio etc) to be backed up manually from the local NAS and stored offsite on a weekly or monthly basis).
- Users on the field should be able to backup small files from the field to the first NAS in the main office.
Note:the internet bandwidth we have available is only 500 kbps (we are in Tanzania where internet is still very expensive).
Can one of you experts please advise how I should go about achieving these goals. Which is the best (inexpensive) software i can use?
