Keep Google Drive mirrored to Dropbox, OneDrive, Box, S3, R2 or B2 on a schedule you choose. Incremental after the first run, two-way if you want both sides editable, and always previewable before anything is deleted.
No credit card. Free plan includes 2 GB of transfer every month.

Runs on our servers on your schedule — no desktop client, no machine left switched on.
The problems people bring us, and what we do about them.
“Sync clients need my laptop on, and I keep closing it.”
Syncrix runs server-side. A schedule fires whether your machine is on, asleep or in a suitcase.
“I moved company files and half the folder structure broke.”
Folder trees are recreated exactly at the destination, and every run is logged file by file so you can see what happened instead of guessing.
“Mirror sync scares me — one wrong setting and files get deleted.”
That is exactly why every rule has a dry run: it lists the copies, updates and deletions it would perform, before it performs any of them.
“Shared drives and team folders never migrate cleanly.”
Shared drives are supported as their own provider type, so team content can be mirrored the same way personal folders are.
Incremental sync that skips unchanged files
Size and modified-time are compared against the previous run, so a daily sync of a large Drive moves only what actually changed.
Mirror and two-way modes
Mirror makes the destination match the source (including deletions). Two-way keeps both sides editable and resolves conflicts by newest-wins, keep-both, or asking you.
Dry-run preview before anything is deleted
Mirror mode can delete files at the destination, so every rule can be previewed first: exactly which files would be copied, updated or removed — before a single byte moves.
Nothing is stored on our servers
Files are streamed straight from the source cloud to the destination. Once a transfer finishes, no copy of your data remains with us — we keep only file names and sizes needed to resume the next run.
Unified File Explorer
Browse two clouds side by side and drag files between them directly, without a sync rule, when you just need something moved once.
Include and exclude patterns
Glob patterns keep node_modules, caches and giant scratch folders out of the backup so you don't pay to move junk.
Review the list, then run it for real. Mirror mode never deletes anything you haven't seen first.
Handing a tool access to years of files deserves scrutiny. Here is exactly what happens.
No copies kept
Files stream from source to destination. Nothing remains with us after a transfer — only names, sizes and timestamps so the next run can skip unchanged files.
Tokens encrypted at rest
Cloud credentials are encrypted with AES-256-GCM and never written to logs. Disconnect a cloud, or delete your account and its data, whenever you want.
Least access we can ask for
For Google Drive we use the drive.file scope — we can only touch what you pick or what we create. Your data is never used to train AI models.
Connect Google Drive and the destination cloud (both take about a minute via OAuth).
Create a sync rule: pick source and destination folders, then a mode — incremental, mirror or two-way.
Run the dry-run preview and confirm the plan looks right.
Set a schedule and let it run. Failures retry automatically and notify you.
No. Everything runs on Syncrix's servers, so scheduled syncs happen even with every device switched off.
Only the files and folders you select through the Google Picker, plus files we create. We use the drive.file scope, which cannot see the rest of your Drive.
Yes — two-way mode keeps both clouds editable, with a conflict strategy you choose (newest wins, keep both, or ask).
The job retries automatically up to three times, resumes from where it stopped, and emails you (plus Discord/Telegram if configured) if it still cannot finish.
Free covers 2 GB of transfer a month, two clouds and one rule. Pro is $9/month for 100 GB, ten clouds, ten rules and scheduling; Business is $29/month for 500 GB.
