01 · Plan & policy
Decide where every copy goes.
Set a policy for the archive: which destinations it writes to, and therefore how many copies it keeps. Build it for the shape the 3-2-1 rule asks for, three copies across two kinds of media with one kept offsite, and the archive reads Covered once every destination in the policy holds a verified copy.
02 · Archive
Write every copy in one operation.
Point Hiberden at a folder and archive it once. The same operation writes every destination in your policy (local disk, cloud, and tape), and the catalog records where every file landed. No juggling three separate vendors' tools.
03 · Verification
A copy doesn't count until it's read back.
When Hiberden writes an archive, it takes its fingerprint: a checksum that changes if even one bit of the data does. Then it reads every copy back from the drive, the share, the bucket, or the tape it just wrote, and checks the fingerprint again. Match, and the copy is proven identical, byte for byte. Miss, and the copy fails. An archive shows Covered 3 of 3 only once every copy has passed, so a bad copy surfaces now, not years from now.
And it keeps checking. Set a schedule once and Hiberden quietly re-reads your disk and NAS copies in the background, oldest first, so silent decay on a copy nobody has opened in three years still gets caught. Quick checks for routine sweeps, full checks when the answer has to hold up.
Covered 3 of 3
04 · Restore
Find any file, restore from the best copy.
Search the catalog for a file across every archive and every copy, then restore from whichever is fastest or closest. Open formats, no lock-in: nothing is held hostage, and nothing has to be migrated later.
