Backup with limited file version history

Question

Data synchronization

Tired of searching, can you recommend software for regular backup that meets the following criteria:

1. Incremental backup, but such that the latest version of all files is centrally located in one directory - in fact, a mirror
2. Storage of no more than N previous versions of files
3. Packing everything in one
encrypted ZIP the current zip is the largest, because is a mirror, the rest are smaller, contain previous and deleted versions of files, with the timestep of the corresponding backup
4. not weigh a ton
5. scheduled execution, and by “connecting a disk”

Answer 1

SyncBackPro is capable of 1,2,4,5
encryption + versioning in case of packing each file into a separate archive
Encryption-versioning in case of packing into one archive
Therefore, encryption was made by third-party means

Answer 2

I solved this problem simply.
1. Made an S3 account on Amazon
2. Installed s3cmd from ports
3. Wrote a php script to create an incremental backup and base ... a two-week history of archives is tracked, all old ones are deleted, when synchronizing with S3, old backups are also deleted.

Answer 3

If you drop the 3 and the refinement, then rsnapshot (which is based on rsync ) is the perfect solution.
It's in GNU/Linux. If you have a Microsoft brainchild, then you should probably look at something else, but I'm not strong here.

Answer 4

take a look at rdiff-backup . As for 3, I'm not sure, 1 and 2 seem to be able to. 5, you will probably have to configure it yourself, I think the Windows scheduler can handle it.

Answer 5

Your point 1, together with 2, and even the 3rd, is not feasible.
What you can do:
Take Cobian Backup
Set up two tasks:
1st task - Incremental backup, taking into account the archive attribute, backup depth - as much as you need, make the archive full - as you need, I usually set it for the weekend. Those. if you need a rollback for a month -
depth 30, full archive - every 7.
2nd task - Dumb copying to one folder, without taking into account the archive attribute, without removing the archive attribute.
Target folder or partition - encrypt EFS, BitLocker, TrueCrypt in the end.

Answer 6

ssd is in principle a good thing - I would put the OS on one SSD big and good, on the second ssd it takes out frequently used data with fast access time - virtual machines, databases, and would store their backups on ordinary screws, better in a raid
