Sage 50 Backup & Restore
A single failed drive shouldn't be able to erase your books. We set up reliable, scheduled Sage 50 backups, move your company file safely to a new computer, and recover corrupted or failed backups. For businesses across the United States and Canada.
(805) 219-7294Quick answer
Back up in Sage 50 with File → Back Up (or a schedule), and restore with File → Restore. Keep a local copy plus an off-site or cloud copy, and test a restore now and then. Your company is a .SAI file plus its matching .SAJ folder — a backup safely packages both.

When Sage 50 backups become a problem
If two or three of these ring true, your data isn't as safe as you think — let's fix it before something goes wrong.
No real backups
Backups are manual and easy to forget, or they all sit on the same computer as the live file.
Restore won't work
You tried to restore and got an error, a version mismatch, or a file that won't open.
Moving computers
New PC or server and you're not sure how to move the company file across without breaking it.
Corrupted file
The file is damaged, your last backup failed, and you need recent data back fast.
What we do
What our Sage 50 backup help covers
Off-site & cloud copies
A second copy kept off the machine — external drive, network, or cloud — so one failure can't take everything.
Move to a new computer
Backup, install, and restore on the new machine — data service and users configured so it opens first time.
Corrupted-file recovery
Data-integrity checks, rebuilds, and restoring from the last good backup to get your books back.
Restore testing
We actually test a restore, because a backup you've never verified isn't a backup you can trust.
A backup policy
A simple written routine — what's backed up, how often, and where — so it keeps working after we're done.
How it works
Backing up & restoring Sage 50
The safe routine we set up for clients — and the same steps we follow when we recover a file.
Back up
File → Back Up creates one compressed file from your .SAI and .SAJ data. We schedule it to run automatically every day.
Copy off-site
That backup is copied to a second location — external drive, network share, or cloud — so it survives a dead PC.
Restore & verify
File → Restore rebuilds the company from a backup. We test it so you know recovery works before you ever need it.
Questions
Sage 50 backup & restore — FAQs
How do I back up my Sage 50 company file?
In Sage 50, use File then Back Up to create a compressed backup, or set a schedule so it happens automatically. We recommend keeping copies in more than one place — a local drive plus an off-site or cloud copy — and testing a restore now and then so you know the backup actually works.
What are the .SAI and .SAJ files in Sage 50?
In the US edition, your Sage 50 company is a small .SAI header file plus a matching .SAJ folder that holds the actual data. Both must stay together with the same name to open the company. A backup packages them into a single compressed file you can restore later, which is safer to copy or move than the raw data folder.
How do I move Sage 50 to a new computer?
The clean way is to make a full backup on the old machine, install the same Sage 50 version on the new one, then restore the backup there. We handle these moves end to end — including the data-service and user setup — so the file opens correctly and nothing is left behind.
Can you recover a corrupted or failed Sage 50 backup?
Often, yes. We work from the most recent good backup, run Sage's data-integrity and rebuild tools, and reconstruct recent transactions where needed. Success depends on how the file was damaged, so the sooner you stop working in the file and call us, the better the outcome.
How often should I back up Sage 50?
Daily for any file people post to every day, and always before a year-end close, a major update, or a data cleanup. Scheduled automatic backups plus one off-site or cloud copy is the setup we put in place for most clients so a single failed drive can never wipe out your books.
